Encouraging findings about long-distance transport

New research shows that horses transported long distances with a commercial shipping company had low risk of associated health problems.


A large-scale study of horses transported long distances with a commercial shipping company found a low risk of associated health problems.


Previously, much of the data on equine travel risks was gathered using horses bound to slaughter facilities, which the researchers say is not applicable to horses transported for other reasons.

“You cannot transfer the findings from papers on the transport of slaughter horses to the transportation of sport horses because the vehicles are completely different,” explains Barbara Padalino, DVM, who conducted the study as part of her doctoral work under the supervision of Gary Muscatello, BVSc, PhD, at the University of Sydney. “Slaughter-bound horses usually don’t travel in single stalls. They are transported in higher density, and often these horses are not tamed and have no travel experience.”

To gather data more reflective of sport and pleasure horses, Padalino and fellow researchers reviewed the records of a commercial transportation company that regularly moves horses between the east and west coasts of Australia. Information was provided on all 1,650 horses the company transported along the same route from April 2013 to April 2015.

“The trip consisted of four stages,” says Padalino. “Sydney to Melbourne [10 hours], Melbourne to Adelaide [eight and a half hours], Adelaide to Kalgoorlie [24 hours] and Kalgoorlie to Perth [six hours]. After each stage, horses were given a 12-hour rest period. The total duration of travel was approximately 85 hours with approximately 49 hours in transit and 36 hours for rest stops.”

At the collection stable and rest points, horses were individually housed in walk-out rubber-lined stables and/or paddocks that were used only for horses in transit. Padalino adds that the transportation company was well-respected and well-run, following guidelines provided by the Australian code of livestock transportation.

The data showed that 97.2 percent of the horses arrived at their destination with no signs of disease or injury. Among the few horses who did have problems, the most common were respiratory illness (27 percent), gastrointestinal issues (27 percent), fever (19 percent) and injuries (15 percent). There were four transportation-related deaths, making the overall death rate .24 percent.

Horses were more likely to hurt themselves in the early hours of the trip. “Injuries are often associated with misbehaviors, such as refusing to load or kicking in the truck,” says Padalino. “It’s been reported that the first hour of a journey is always the most stressful for horses. During that time horses tend to move more, try to escape more and lose their balance more.”

In addition, the researchers found that horses transported in the spring were more likely to develop gastrointestinal or respiratory problems. This, they say, may reflect higher temperatures at a time when many horses still have winter coats, or challenges posed to their immune systems by hormonal fluctuations or increases in pollen or other allergens associated with the season.

Padalino says this low illness and injury rate is encouraging. “This percentage is actually really good, considering that we examined one of the longest journeys which horses can do worldwide in a very hot country. This figure tells us that safe transportation of horses is possible when done by experienced people.”

For trips of more than 20 hours, she recommends using a reputable shipping company, inspecting the transport vehicle and having a full veterinary exam performed ahead of time to identify any subclinical illnesses that the stress of transportation may exacerbate.

How Studying Biomechanics Enhances Your Dressage Training

The study of biomechanics provides the basis for understanding multiple facets of dressage.

What sets apart the horse who has amazing expression in his work from others? If you were to ask an engineer or someone who studies movement, he or she would use biomechanics to analyze the question. Biomechanics is the study of the forces that affect movement of the body. It examines how muscles, bones, tendons and ligaments operate together for a horse to walk, passage or perform lateral movements.

Biomechanics is the study of the forces that affect movement of the body. It examines how muscles, bones, tendons and ligaments operate together for a horse to walk, passage or perform lateral movements. (Amy K. Dragoo)

Different anatomical structures work in synchrony. The bones are the support structure. They are rigid and provide a framework. The joints’ anatomy dictates their degree of mobility (range of motion). Ligaments are the connections between bones, frequently involving joints. They are strong and flexible, allowing for distinct movement of a joint while providing stability. The muscles serve to propel the horse and to stabilize. For every muscle that moves a joint in one direction, there is typically a countering muscle that can pull the joint in the other direction. When the opposing muscles work in unison, both firing in balance, they stabilize joints. This equilibrium keeps the legs rigid when weight- bearing, the back from breaking and the head elevated and in motion with the horse’s movement.

The study of biomechanics provides the basis for understanding multiple facets of dressage, such as how neck position affects the forehand, back and hindquarters. It explains why it takes time for young horses to develop the strength to travel uphill with self-carriage and with an extended forehand. It also reinforces the importance of proper rider core strength and position to support the horse. It is necessary in comprehending how injuries and resulting pain can prevent horses from progressing and performing.

Biomechanics explains how riding with the neck lowered affects the entire length of the horse. This position produces traction through the ligaments and muscles of the topline, of the neck and back, causing the back to flex, or round. It moves the center of gravity forward with more weight distributed to the forehand, thus strengthening the muscles suspending the thorax. With the back flexing, the workload of the abdominal muscles increases. The advantages of incorporating exercises in a lowered neck position include strengthening the areas mentioned above.

An understanding of biomechanics can facilitate riding and training. Research has shown that the muscles involved with suspending the thorax within the shoulder blades affect the horse’s ability to move in an uphill carriage with a protracted forehand stride. These “sling muscles” raise the withers within the shoulder blades as they become stronger. The sling muscles consist of the pectoral muscles in the chest area and the serratus ventralis muscles between the rib cage and the scapula. Strength and training of these muscles lifts the front. As the front end raises, the hind end can sit and accept more weight to propel the horse.

Working in an uphill carriage or with the neck lowered can have positive and negative effects on a horse’s body depending on the nature of his biomechanics. The constructive effects of work done correctly and progressively are strengthening of the target areas and the horse learning to carry himself. Training with the head lowered could potentially stress an existing front leg problem by shifting the center of balance forward. By the same token, it can be a helpful position in strengthening a horse with kissing spines (impinging dorsal spinous processes). An uphill position may not be obtainable for a horse with sacroiliac or hind-limb discomfort.

In the case of a horse who exhibits some kind of physical discomfort during training, a veterinarian frequently correlates his or her diagnosis of a specific area of soreness to what a rider is feeling or a sign the horse is showing. An example would be lower neck pain on the right preventing a horse from bending to the right or not picking up the right lead. Horses can have multiple areas of soreness. Biomechanics is key in understanding what problems are causing the signs the horse is exhibiting.

Biomechanics encompasses most aspects of riding and training. It is the science behind how a saddle interacts with the horse’s back, how a horse compensates for an unbalanced rider, what a rider feels with a lameness and more. It is not a necessity for a rider to comprehend all aspects of biomechanics of the horse, although it does enhance the understanding of training and riding.

Resources for Studying Biomechanics 


Biomechanics can be approached from a superficial level to an in-depth study. The Internet is always a source with both valid and less-than-reliable information. Dr. Hilary Clayton has been one of the greatest sources of research and literature pertaining to equine biomechanics. She appears online in videos and articles and has papers available on many biomechanics topics. For more comprehensive studies there are books on equine biomechanics. Biomechanics and Physical Training of the Horse by Jean-Marie Denoix is written for the rider/trainer with an overview of anatomy, biomechanics and analysis of specific riding exercises. The Dynamic Horse by Dr. Hilary Clayton thoroughly covers the science of biomechanics.

How To Teach Your Horse to Bend

Trainer Jordan Linstedt offers advice on how you can make your horse more supple.

Q: My new horse has a lot of potential, but I’m having trouble teaching him to bend around corners and be more flexible. Any hints?

JORDAN LINSTEDT

A: To bend well and be flexible, your horse must develop a great deal of strength in his back and hindquarters— in fact, in his entire body. To travel correctly around a turn or circle, your horse must bend his body through his rib cage, rather than simply turn his nose to the inside. It takes time to develop the balance and strength necessary to do this well, so be patient with your horse. Here are some tips to get you headed in the right direction:

Start by evaluating your rein contact. A good bend comes from your legs, not the reins. Ideally, you should use twice as much leg aid as you do hand. From the very beginning, you want to have a light, elastic connection to your horse’s mouth. As he grows stronger and uses his back and body more, he should trust your hands enough to move forward into a more solid contact, but it should never become heavy. I aim to feel no more than 1 to 2 pounds of pressure in each hand.

Your contact with a young and/ or learning horse also needs to be equal on both reins. Before you can ask him to bend properly, he must travel straight. And he can’t be straight if your contact is uneven. So concentrate on riding him forward into an even connection in both reins.

Also check that your position is centered and balanced, with your weight distributed evenly down through both legs. The better balanced you are, the better balanced and straight your horse will be. If your position tips too much to one side or the other, you’ll feel the opposite foot get lighter in the stirrup. To correct this, step down firmly into that stirrup iron.

When your balance and contact feel reliably consistent, try this spiral exercise:

Begin at the trot on a 20-meter circle. Shift your weight slightly onto your inside seat bone, still keeping the rest of your weight equally distributed through both legs and maintaining your even contact in both reins. With your inside leg at the girth and your outside leg just behind the girth, think of using your legs—more than your reins—to ride your horse’s rib cage to the outside of the circle.

Now gradually spiral in, taking several rotations to shrink the circle to a diameter of 10 to 15 meters, depending on what your horse can do comfortably. (Don’t reduce the size of the circle to a point where he loses momentum or seems to be struggling in any way.) As the circle gets smaller, your horse naturally will have to bend more. Be careful not to over-flex his nose to the inside—remember, the bend should be as much in his rib cage as in his neck. Also be sure to stay connected to him with your outside rein and outside leg.

When you reach the smaller circle, slowly spiral out again. Repeat this once or twice and then do the same thing in the other direction. If you continue to practice this exercise over time, you’ll begin to feel his body bend around your inside leg, with your outside rein and leg controlling the shape and size of the circle.

As your horse’s strength develops, use your diagonal aids to introduce a slight counter bend. Trotting again on a 20-meter circle, reverse your leg positions, moving your inside leg just behind the girth and your outside leg on the girth, and ask your horse to bend his body slightly to the outside for a few strides while staying on track on the circle. You can play with changing back and forth between the true bend and counter bend on diagonals, serpentines and along the rail. This will gradually improve his suppleness.

When your horse begins to produce a good bend and counter bend, if you know the aids for performing a leg-yield, use that as another suppling tool. As you trot across a diagonal, several strides before you reach the far corner turn slightly toward the new direction (for example, if you’re about to turn to the right, apply your right-bending aids) and ask for a few steps of leg-yield into the corner (in this example, moving away from your right leg). This will help to get your horse deeper into the corners while improving his balance and bend.

Throughout this training process, whether you’re a beginner or advanced- level rider, you’ll progress most quickly if you have an eye on the ground—a trainer or other experienced horse-person watching your work to confirm that you’re doing it correctly. With this support—and a great deal of patience—you can teach any horse to bend.

Rising eventing star Jordan Linstedt, 24, began riding at age 2, when her mother ponied her on trails. As a teenager, with guidance from Olympic eventer Todd Trewin, she brought several off-the-track racehorses up through the levels. 

When she was a senior in college, Jordan’s parents purchased a 17.3-hand imported Irish sport horse gelding, Tullibards Hawkwind, or Jack. Six years later, after working with several top trainers, including British Olympic gold medalist Leslie Law, Jordan and Jack completed their first four-star event at the 2012 Rolex Kentucky Three-Day Event with a steady, clear cross-country round. 

Jordan currently trains and teaches at her mother’s Saddle Rock Stables in Redmond, Washington. She also takes online classes at the University of Washington, where she is studying society, ethics and human behavior.

7 Things you may not have known about DMSO

This odiferous compound has become a common treatment for a variety of inflammatory conditions. Here are a few interesting facts about DMSO's history and action.

Two decades ago, if you mentioned dimethyl sulfoxide (DMSO) around the barn you may have gotten puzzled looks in response. Back then, this industrial solvent turned anti- inflammatory therapy was relatively new to the horse world, and even if people had heard of it they viewed it as an unusual or even mysterious option.Since then, DMSO has gone mainstream. It is approved by the Food and Drug Administration (FDA) for topical use on horses, but veterinarians regularly use the chemical “off-label” in other ways to treat a wide array of inflammatory conditions, from laminitis to neurological problems. When the DMSO’s distinctive garlicky smell wafts through the barn these days, people are more likely to nod knowingly than wonder what’s going on.

Nonetheless, DMSO is a little like aspirin---something that many people use without necessarily thinking too much about how it works. But learning more about DMSO may help you appreciate how it can be useful in maintaining your horse’s health and comfort. So here are seven things you might not know about DMSO.

1. The therapeutic properties of DMSO were discovered more or less by accident.

A byproduct of paper production, DMSO was first developed as an industrial solvent. As people worked with the chemical, they noticed that if they spilled a bit of DMSO on their hands a distinct garlicky taste would be on their tongue shortly thereafter. This intrigued chemists, who began researching how the liquid could so quickly pass through skin and mucosa, but the work was generally limited to exploring non-medical applications.

Then, in the 1960s, Stanley Jacob, MD, began investigating DMSO as a preservative for organs destined for transplants. Work done in his laboratory soon sparked a rush of research into DMSO’s possible medical uses.

By 1965, however, the FDA closed down clinical trials citing safety concerns. Since then, DMSO has been approved for some specific applications. In human medicine, these include use as an organ preservative and as treatment for a bladder disease called interstitial cystitis. In 1970 it was approved for topical use in horses and dogs.

2. DMSO’s anti-inflammatory properties come primarily from its antioxidant action.

DMSO is classified as a nonsteroi- -dal anti-inflammatory drug (NSAID), just like phenylbutazone (“bute”). Unlike bute, however, DMSO controls inflammation primarily by acting as an antioxidant.

You may be more familiar with anti-oxidant sources in nutrition, such as vitamin E or lycopene, but DMSO has a molecular structure that allows it to function in the same way. Specifically, DMSO binds with “free radicals,” which are oxygen compounds---leftovers from normal biochemical reactions---that damage or destroy healthy cells. These free radicals are often the byproduct of inflammation and, in turn, cause more swelling and inflammation as they accumulate. DMSO is a free radical scavenger that slows or halts this process.

When used to control inflammation in strains and other soft-tissue injuries, DMSO is usually applied topically. However, it may also be injected into a target area when an injury occurs in particularly dense tissue, such as a bowed tendon, or the site is difficult to reach. A veterinarian may administer DMSO orally or intravenously in the early stages of laminitis to try to slow or halt the inflammatory cascade.

3. DMSO draws fluid from tissues.

DMSO is a hygroscopic compound, meaning it attracts water. This property makes the compound especially versatile. For instance, it can reduce edema0 in swollen limbs and is often used as part of a “sweat” to combat stocking up. DMSO can also reduce swelling in the brain and spinal cord, which can be literally lifesaving in diseases like West0 Nile encephalitis. DMSO may be used to draw fluids out of the lungs in cases of acute pulmonary edema.

Because it pulls water from tissues, DMSO has a diuretic effect, meaning it makes a horse urinate more. This can help flush toxins from the body more quickly. With this action in mind, DMSO is often given intravenously in the treatment of cantharidin poisoning (blister beetle toxicity), to lessen the effect of the toxin on the kidneys and intestinal tract. After episodes of tying up, DMSO may help horses eliminate waste products of muscle breakdown through their urine more quickly. The diuretic action of DMSO, however, can make it unsafe for horses who are dehydrated or in shock. It can further dehydrate these animals or dangerously lower their blood pressure.

4. DMSO can carry other substances through the skin.

DMSO’s molecular structure allows many substances to dissolve completely within it. It also allows the chemical to transport these dissolved substances through cell membranes without damaging them, even if these sub- stances wouldn’t be able to pass through on their own.

For instance, treating rainrot or other skin infections can be difficult because the responsible organisms are buried deep under the skin or crusty, painful scabs. However, a mixture combining antibacterial medication with DMSO can pass through the skin and reach the affected area. For the same reason, DMSO is often added to antifungal medications for treatment of eye conditions and sometimes to steroids for targeted, topical anti-inflammatory treatment.

It’s important, of course, to avoid inadvertently mixing DMSO with potentially toxic substances. You wouldn’t want fly spray crossing into your horse’s bloodstream, for example, so take care to avoid applying DMSO to your horse if he has recently been sprayed. Likewise, avoid mixing DMSO with substances that could be toxic if ingested, such as organophosphates or mercury salt. Also be mindful that the effects of some drugs, such as corticosteroids and atropine, are intensified when mixed with DMSO, so doing so needs to be done with caution under a veterinarian’s direction.

5. DMSO may provide pain relief on its own.

Although it’s commonly mixed with compounds to provide pain relief, some studies suggest that DMSO alone has analgesic properties. Research shows that DMSO slows or blocks conduction of impulses along nerve cells, which in effect reduces pain from musculoskeletal injuries, postoperative incisions and other sources. Relief is only temporary ---lasting up to a few hours---because as the DMSO dissipates, normal nerve function returns. It can be combined with other pain-relieving drugs, however, to extend the analgesic action.

If it seems like DMSO has a variety of purported actions, that’s true. It’s nothing if not versatile. Some applications of DMSO combine all of these: For instance, it is often used in surgical colic cases to reduce the risk of tissue adhesions due to inflammation and poor circulation; some surgeons think that it may also provide some pain relief in the hours following surgery.

6. DMSO is a prohibited substance in some sports.

DMSO isn’t technically a medica- tion, but various competition organizations treat it as one when it comes to drug testing.

The Fédération Equestre Internationale (FEI) classifies DMSO as a “controlled” prohibited substance, meaning that although it may have some therapeutic value, DMSO has the potential to affect a horse’s performance and its use is forbidden or limited. As of January 2018, the threshold of DMSO allowed by FEI was 15 micrograms per milliliter in urine or one microgram per milliliter in plasma. The Jockey Club allows 10 micrograms per milliliter of plasma. If you compete with your horse, check any governing association rules regarding DMSO use.

Also keep in mind that because DMSO can move other materials through the skin, combining it with other medications could result in a violation of thresholds for both. For instance, mixing DMSO with the topical NSAID Surpass (diclofenac) can cause an increase of the medication in the bloodstream, leading to a disqualifying test. The medication guidelines for the United States Equestrian Federation state, “Do not apply diclofenac cream in combination with any other topical preparations including DMSO, nitrofurazone, or liniments.”

7. DMSO use in horses hasn’t been studied extensively.

A search of a research database will turn up a good sampling of peer-reviewed papers on DMSO use in horses, but the compound has gotten far less scientific scrutiny than have medications developed specifically for therapeutic applications. Some studies about DMSO’s effects contradict each other, particularly in regard to its use for treating arthritis.

Scant information is available regarding dosing. Often veterinarians rely on their own experiences and those of their colleagues in deciding when and how to use DMSO. That is why it’s important to let your veterinarian lead the way when it comes to treating your horse with this compound.

Whether applied topically, orally, intravenously or by injection, DMSO requires careful handling. But its versatility means that if you haven’t used it so far, you probably will eventually. If you do, keep these basic facts in mind to make sure your horse benefits fully from this unusual preparation.

5 Show-Ring Tips to Help You Ace Your Hunter Rounds

Are you gearing up for show season? Here are a few tips from some of our favorite experts to help you and your horse perform your best hunter rounds.

Tom Brennan and Buttoned Up looking confident and focused during their hunter round at the Upperville Horse Show. 
1. First Impressions Count

Judges look at the whole picture, says USEF 'R' judge Patrick Rhodes. “Is your horse turned out well? Are your boots polished? Does your coat fit? If the overall look and appearance is happy and balanced and the horse has a certain presence, I get excited to watch your round.”

What you do next sets the tone for the judge. Patrick likes to see a rider start the round efficiently and confidently with an “I got this!” attitude. “Pick up a nice gallop in a rhythm and pace that suits your horse, then go straight to the first jump,” advises Patrick. “Don’t tour the whole ring.”

2. Wow the Judge Right Away

When deciding how to pin hunter classes, judges ask themselves, “Which of these horses would I most like to ride?” With rounds lasting only 90 to 120 seconds, says hunter rider, trainer and 'R' judge Tom Brennan, there’s not much time to demonstrate that your horse is the answer to that question. From the moment you enter the ring to the moment you leave, your performance must exude ease and confidence. Communication between you and your horse should be nearly invisible. Nothing should distract the judge’s attention from his round. In fact, the best riders seem to melt into the scenery—all you notice is the horse. Exceptional hunter riders allow the horse’s expression to come through so every obstacle he meets is simple, forward and enjoyable to watch.

3. Ride Preventatively

Before you ride any course, try to anticipate potential trouble spots for your particular horse, says top hunter rider Keri Kampsen. If he’s the type who loses momentum, bulges out and drifts toward the in-gate, plan how you will ride past it. If it’s on the end of the ring or in a corner, make your lead change early, then shave a little off the turn. Carry your whip in your outside hand and raise it slightly so he can see it out of the corner of his eye. Turn his head away from the in-gate and give a cluck to encourage him to keep cantering past it.

A lot of mistakes occur because of poor track riding: cutting corners, overshooting turns, etc. The best remedy is to stay focused and ignore things that distract your horse. Once your eye is on a jump, don’t look away. If you keep riding to it with determination, he will eventually catch up to you.

As she passes the in-gate, Keri Kampsen keeps a slight inside bend and closes her outside leg to keep her horse, Autumn, focused and looking ahead to the next jump on course. 

4. Maintain Rhythm to Ace the Long Approach

It’s most hunter riders’ nightmare: the long approach to a single fence, says top hunter/jumper rider Nick Haness. This question can be found at the beginning, middle or, most often, at the end of hunter courses at every level. For the horse, the long approach can be tricky if it’s going into or away from the in-gate, encouraging him to rush toward home or be sluggish going away. But this course element is mostly a rider challenge. With so much time to think about how things are going, what you should be doing or not doing and how you will find the distance to the fence, it’s hard to resist the temptation to do something.

Most often, riders interfere with the horse too much. They change the rhythm, move forward or come back because they have a doubt about the distance. Or they over- or under-steer. All of these tendencies circulate back to the mental aspect of the game: It’s hard to sit tight when you have so much time to think. In most cases, giving in to such temptations backfires on you. An example is seeing a distance on approach, then changing your mind and moving up unnecessarily. This causes your horse to take that fast, extra step—a chip—which likely wouldn’t have happened if you had maintained the same canter even if the distance was a little bit off.

5. Control Your Pace

Having an inconsistent pace not only destroys the nice flow the judge is looking for, but it also interferes with your ability to find the distances to the jumps, says top hunter rider Kristy Herrera. If you approach each fence in a reliable working canter—the canter that hunter courses are generally set for—you’ll have three options for meeting the correct takeoff spot: maintaining your current pace, moving up or waiting. If you approach the jump either too slowly or too quickly, that narrows your options. For example, if you’re going too fast, you’ll arrive at the jump at the end of your horse’s stride—the biggest stride he can make comfortably—which means you’ll have only two options: Either you’ll arrive at the fence on a very long, flat distance or you’ll be forced to shorten his stride at the last minute and get to a too-deep takeoff spot.

How Do I Open Up My Horse’s Stride in Combinations?

Learn how you can help your short-strided horse make the distances when jumping combinations.


A reader asks: "My horse has a shorter-than-average stride and sometimes has trouble making the distances in big combinations. If I try to help him by going faster in the approach, he gets too flat and knocks rails down. He’s a wonderful jumper otherwise and I’d hate to give up on him. What can I do to help him with these big combinations?"

Top hunter/jumper trainer Scott Lenkart offers the answer:

This is a fairly common problem that is solvable in most cases. Horses tend to shorten their stride when they’re nervous—and they often get nervous when you ask them to speed up. So pushing your horse to go faster into big combinations is counterproductive. Instead, the key is to learn how to help him relax into his most comfortable pace. Once he’s relaxed, it’ll be easier to encourage him to stretch his stride out, bit by bit. This takes lots of practice at home.



One exercise that you might find helpful is a simple grid consisting of a small crossrail, followed by a ground pole 9 feet away, then a one-stride in-and-out four strides from the crossrail (about 55 feet). Initially, set the in-and-out at a comfortable distance—about 21½ to 22 feet—to make it feel very doable for your horse. (For horses with a slightly bigger stride, I’d open that distance up somewhat, to perhaps 23 feet.) By trotting into this exercise, you’ll remove any concern about finding the right distance to the jumps. The ground pole will encourage your horse to land cantering after the crossrail, and the set distance will bring you to a nice takeoff spot for the “A” element of the combination. This is very important, as one bad distance to the “in” of an in-and-out can make any horse worry.

Build the in-and-out as either an oxer to a vertical or a vertical to an oxer, whichever is more comfortable for you and your horse. Make both jumps fairly small at first and ramp the oxer (build the front rail lower than the back rail). Add a ground line in front of each jump to make it more inviting.

As you trot into the grid, focus your eyes beyond the “B” element of the in-and-out. Stay in a light, forward seat, with your hands in front of your body. To avoid causing your horse to knock down a rail on takeoff, wait for him to leave the ground and then follow with your hand and upper body. When you land from “A,” rock back into your two-point position to make sure your leg is underneath you and your eyes are looking ahead, then ride to “B” in the same light, forward position. If the initial distances feel too long or short, adjust them accordingly to make them as comfortable as possible for your horse.

When this is riding well, widen the oxer a little bit. Always widen the oxer before raising it—and never do both at the same time. Then gradually increase the heights of the in-and-out fences. Keep the “out” jump smaller than the “in” jump, so it’s less intimidating. As your horse’s confidence grows, gradually lengthen the distance in the four-stride line to about 60 feet and the distance in the combination to 24 feet, always keeping the jumps very inviting, so he never feels threatened. So long as he stays relaxed, he’ll begin stretching his stride automatically. When that’s going well, lower the jumps again and try the opposite configuration (for example, oxer-to-vertical if you started with vertical-to-oxer).

To transfer these new skills to competitions, be sure to minimize any stress that might make you—and, thus, your horse—nervous. Allow plenty of time to tack up and get to the ring so you’re not rushed. Warm up with lots of flatwork to loosen up, relax and stretch your horse, spending more time in whichever gait he finds most relaxing. Use ground lines to help him arrive at good distances. Build his confidence by working your way up to a slightly wider (but not higher) oxer than you might see in the ring. Then finish with a somewhat smaller vertical or rampy oxer—whichever seems to suit your horse best—with a ground line.

On course, approach combinations in a normal canter. Stay in your forward seat and ride just the way you did at home. Remember to be patient on takeoff, then follow your horse’s motion with your hand and upper body. If he feels a little sticky, encourage him with a cluck.

Keep in mind, inconsistent riding can make your horse nervous. If he knocks a rail down—either at home or at a show—don’t overreact. Just continue practicing and doing your homework. As he begins to trust you and relax, he’ll learn to stretch his stride in the combinations as needed.

Dressage Schooling Notebook: An Exercise of Circles

Improve your horse’s straightness and contact with this dressage training exercise from Gerhard Politz.

Exercise:

Walk or trot your horse on a 20-meter circle in the direction that he feels hollow—where he tries to avoid contact. At the centerline, ride a change of rein and do a 10-meter volte.



Benefits:


  • Straightens your horse.
  • Encourages your horse to stretch his body into the rein on his hollow side and, eventually, helps you get more equal contact on both reins.


How to Do It:


  1. You first need to determine which is your horse’s stiff side and which is his hollow side. On his hollow side, he will have a tendency to bring his haunches in and fall through his outside shoulder. Falling through the outside shoulder becomes more obvious when riding circles or lateral movements such as shoulder-in. As a result, the contact on the outside rein becomes stronger because your horse tries to avoid contact on his hollow side.
  2. Begin riding a 20-meter circle on your horse’s hollow side in an energetic walk, working trot or an impulsive collected trot, according to your horse’s capabilities and stage of training. Let’s assume your horse is hollow to the right. Ride a 20-meter circle to the right. You will feel that the contact on your inside, right rein is lighter than on the outside, left rein. The measure of difference in the contact is related to the severity of stiff-versus-hollow side
  3. When you reach the centerline, ride a 10-meter volte to the left, to the outside of the 20-meter circle. Use your inside, left rein to bend your horse quite obviously in the neck. When your horse releases the inside muscles of his neck, his neck becomes somewhat concave. When that happens, immediately lighten the contact on your inside rein and allow your horse to stretch into the outside rein. Your inside leg is at the girth and your outside leg is behind the girth to ensure the bend and to prevent your horse’s haunches from falling out. If you ride the circle in the middle of the arena, you can repeat the outside volte on the opposite side of the 20-meter circle, thus linking two voltes to the bigger circle.
  4. Repeat this exercise several times, and you will feel that your horse is increasingly ready to take contact on the outside rein in the volte. It is important, however, that you keep giving the inside rein on the volte whenever possible. Remember that this is the rein on which your horse wants to be heavy when you ride the 20-meter circle.

Tips for Success:
  • Begin at the walk to introduce and familiarize yourself with the exercise. Pay attention to the quality of the walk and the degree of “forward.” Do not allow your horse to walk “like a snail on vacation.”
  • Make sure you don’t wrench your horse with your hands around the circle and volte.
Variations:

Variations of this exercise improve the straightness and strength of your horse’s hollow side, confirming him in that rein, and make him lighter on the opposite, heavier rein. Your horse will become suppler and more flexible, his collection will be enhanced and his shoulders will become free. Because of the loosening and suppling effects, these variations also help address problems arising from a “passagey” or “hovering” trot. In addition, your riding skills will improve considerably if you strive for meticulously correct execution of the movements.

  • To increase the gymnastic value of this exercise, incorporate lateral work. For example, begin with shoulder-in right on the 20-meter circle. On the centerline, change rein to a 15-meter circle riding haunches-in left. Make sure you often release the inside, left rein on the smaller circle just as you did previously in the volte so your horse takes a better contact on the outside rein. Then at the centerline change rein again to the 20-meter circle to shoulder-in right. Over time, the degree of difficulty can be enhanced by downsizing the 15-meter circle to a 10-meter volte.
  • Vary riding shoulder-in right and renvers on the 20-meter circle. Eventually go from renvers to a 15-meter circle or smaller outside circle in haunches-in.

Before you include lateral work on circles, it is advisable that you acquire good knowledge of riding lateral work on straight lines. It is very easy to misjudge and overdo the bend and angle of lateral movements when riding them on circles. This would throw the horse onto his shoulders and be totally contrary to the purpose of lateral work. Also, make sure you don’t overdo the angles in lateral work and don’t wrench your horse around with your hands since serious drawbacks will occur, such as the horse losing regularity of the gait, impulsion and possibility of collection.

Fit and Fun for life

Margie Engle: Fit and Fun for Life

How a legendary grand prix rider extends her jumpers’ careers without dampening their enthusiasm for the sport.

My number-one priority is always the horse. I’m constantly seeking new ways to extend my mounts’ careers without making them mentally or physically sour. I avoid overdrilling them not just to prevent unnecessary stress on their legs but also because I want them to look forward to their work with the freshest, happiest attitudes possible. I accompany my husband, Steve Engle, DVM, to veterinary conferences to keep up to date on the latest science and strategies for strengthening and conditioning horses while also reducing their risk of injury as much as possible. I also pay attention to methods that trainers use in other disciplines. Here are some of the most important lessons I’ve learned:

1. Minimize the pounding. Over time, concussion may lead to injuries in horses’ feet, joints, tendons and ligaments. The bigger the jumps, the greater the concussion. So small jumps are best for schooling sessions.

2. Avoid excessive repetition. Just as repetitive motions can cause tendonitis in humans, they can lead to muscle fatigue in horses, which, in turn, causes physical structures to break down. This can be challenging in sports like jumping, where a certain amount of practice is necessary for both horses and riders to develop and refine their skills. If you don’t practice at all, you and your horse may not have the required strength and timing to perform to the best of your abilities without risking injuries. So it’s a fine line. Some practice is a must, but change things up before your horse gets sore or bored.

3. Target the entire body. Focusing too much on one body part eventually leads to compensation. For example, if you constantly ask your horse to land on one particular lead, his muscles on one side of his body may fatigue. To compensate, he’ll try to shift the load over to the other side of his body. This is how many lamenesses develop. The stronger your horse’s entire body is, the less risk he’ll have of getting injured. So choose exercises that work both sides of his body equally and also strengthen his stomach, back, neck, etc.

4. Use interval training and cross-training. Event riders are especially good at interval training. They know how to bring their horses’ heart rates up, maintain the intensity for several moments, then ease off to bring the rates back down again. Gradually increasing the number of these interval “sets” improves overall strength and fitness.

I also incorporate the gallop into my jumpers’ routine programs not just to improve their adjustability and get them comfortable at the gait but also to expand their lungs.

Dressage is excellent cross-training and a great way to improve rideability and responsiveness. All horses should be taught basic dressage. If you are able to progress to a more advanced level, the gradual incorporation of collection into your jumper’s routine will strengthen different muscles from the ones he is accustomed to using. When Olympic dressage rider Lisa Wilcox rides my horses, it’s like sending them to the gym: She makes them use their hind ends in brief repetitive sets, asking them to do the equine equivalent of human squats.

5. Work on different surfaces. Riding your horse on a variety of terrain—sand ring, grass ring, trails, hills and even firm surfaces—strengthens different structures in his body and gets him comfortable performing on diverse types of footing. It’s great for his mental health, too.

6. Repeat exercises in both directions whenever possible. Horses’ brains don’t work exactly like ours do. When you perform an exercise and then approach it from the reverse direction, for them it’s like seeing it for the first time. You’ll always get the most out of a lesson if you can do it both ways.

I design my schooling sessions with all of these principles in mind. Below are three of the exercises I use to keep my horses’ programs fresh and effective.

Exercise 1: Football Grid



Setup: Place four poles 3 to 3½ feet apart with a single, adjustable cavalletti support on one end of each pole, arranged so the cavalletti are angled in an alternating fashion. Start with the poles flat on the ground or at their lowest setting.

Step 1
I approach the poles in a collected trot. I normally begin this exercise at the sitting trot to have maximum control of the rhythm and pace, but I use a rising trot on Alter Ego, owned by Lea Allen, because he stays naturally animated in his hind end and is already familiar with the exercise.

Step 2
This is a good example of how the poles help to improve the connection between your leg and hand. By using too much hand and not enough leg, I’ve made it difficult for Alter to lengthen his stride. As a result, he steps into the exercise a little shallowly. His front hoof has landed close to the first pole rather than where I’d like it to be: halfway between the first and second poles.

Step 3
This time through the exercise we have the opposite problem: I’ve used too much leg and not enough hand (see the slight loop in my rein). As a result, Alter extends too much and tries to jump the cavalletti.

Step 4
Finally, we get the connection just right! He’s stepping almost perfectly between the poles, flexing his hocks and knees exceptionally well and stretching his head and neck forward and down, making good use of his back and topline muscles. I can really feel the animation and suspension in his steps here.

Step 5
When Alter feels ready, we rotate the cavalletti to the next height (8 inches), and when that goes well, we move them up to 10 inches. You can tell by the nice curve in his topline that he’s engaging his neck, back and hindquarter muscles to raise his legs higher over the poles, creating a more suspended gait.

Step 6
Finally, we rotate the cavalletti to their highest height (12 inches). Note how much he’s flexing his joints and using his topline. This is a great low-impact way to strengthen his muscles.

This exercise reminds me of the tires that football players run through to improve their agility and coordination. It strengthens a horse’s topline, engages his hind end, increases the suspension in his gaits, teaches him to regulate his pace and gives him a better awareness of where his feet are. At the same time, it improves straightness as well as the rider’s leg-to-hand connection with the horse.

To set up the grid, you can use any equipment that enables you to raise a cavalletti on just one side. I have boxes that I can roll over to create different heights (6 inches, 8 inches, 10 inches and 12 inches). Jump standards would work, too, if yours have holes that go as low as about 6 inches. Place three or four poles about 3 to 3½ feet apart—up to 4 feet apart for bigger horses—with a block or standard next to each pole.

For the first few passes through the grid, set both ends of each pole on the ground so they’re just normal trot poles. Approach them in an active, collected sitting trot. (Sitting trot is ideal because it provides the most control over your horse’s rhythm and impulsion and gives you the best feel of what he is doing underneath you. But rising trot is fine, too, if you’re not comfortable sitting the trot yet.) Wrap your legs down around your horse’s sides so you can feel his hind end and back working. Think of pushing his hind legs forward while creating more suspension in his steps, asking him to march up to the poles.

Trot straight through the center of the poles, then change direction, make a loop and ride back through them the other way. Change direction again, this time turning the opposite way after the poles (if you made the previous loop to the left, make this one to the right), so you end up riding a sort-of figure-eight pattern over them. Focus on riding a very accurate track: straight in the approach, over the poles and afterward, then making nice bending turns. Use the ends of the ring to maximize your straightness in each approach to the exercise.

If your horse is nervous or tries to rush through the poles, bring him down to the walk, remove a pole or two (from the beginning and/or end of the series so the remaining poles are still 3 to 3½ feet apart) and walk over the remaining poles very slowly and deliberately. This will teach him to step in between the poles. When he’s doing that well, go back to trot and approach the poles in a very quiet, controlled manner. After several successful repetitions, add the other pole(s) back in.

Once he is comfortable with the ground poles, raise the alternating ends of each pole so that one end rests on the ground and the other end is raised by the block or standard, set at its lowest height. For example, raise the first pole on the right side, the second on the left, and so on. Approach the grid in the same way, in your sitting trot if possible. Stay connected with your legs and hands so your horse understands he’s still supposed to step over the rails and not jump them.

Repeat this a few times in both directions, praising him each time he does it correctly and taking plenty of walk breaks. Then, if he seems really comfortable with the exercise, raise the pole ends to the next height. Don’t go above 8 inches in your first session. If he has a good first experience and is feeling confident and coordinated, you can start your next session where you left off and gradually increase the height and/or add more poles, if you like. Also, if you feel secure in the saddle, try the exercise a few times without stirrups.

As your horse gets the hang of the exercise, you should feel his energy clearly flowing from your legs into a nice connection in your hands. Each time you go through the poles, try to find a happy balance between your legs and hands. If he slows down and drops behind your leg, ask yourself if you were using too much hand. If he gets flat and fast, ask yourself if you were using too much leg and too little hand. You never want to be rough with either your hands or legs, but instead want to maintain a light connection with both, allowing for and supporting a nice steady rhythm.

You will also feel more spring in his back as he lifts his legs over the poles. This is the elevation and suspension you want to feel—and it’s just the impulsion and “spring-loading” we want for jumping. Once you have a nice connection over the poles, it’s OK to do them at the rising trot. Be sure to continue asking for collection and suspension in each repetition of the exercise.

Remember not to overdrill. Once your horse seems to understand the exercise, repeat it just a few more times before going on to something else. Then incorporate it into your flatwork, doing some lengthening and shortening of the stride, lateral work, canter transitions, etc., elsewhere in the ring in between passes over the poles.

Exercise 2: Double Bounce



Setup: Build three verticals with ground rails on both sides of each, 9 to 10 feet apart from one another.

Step 1
The first time we go through the exercise, we remove the rail from the third vertical, leaving its two ground rails side by side in place. We approach this single bounce in a collected but animated canter. As Alter locks his focus on the first fence, I wait for him to...

Step 2
… jump up to me. I stay quiet in the saddle, keeping my eyes up and my hands softly following his mouth, letting him figure out the exercise.

Step 3
In this moment, Alter is setting himself up for the next jump: His front feet have already touched down and pushed off again while his hind legs are just about to land from the first jump. By engaging his hindquarters, he compresses his body into this tight round shape.

Step 4
As he jumps the second vertical confidently, already focusing on the next ground poles, I stay out of his way, letting the jumps do the work instead of my hands.

Step 5
Now we build the third vertical. I approach the grid in the same canter and stay quiet as he bounces through the exercise. He’s starting to engage his hind end to land and push off immediately. You can tell by his expression that he’s paying attention. The curve in his neck and back and the muscle ripples along his belly show that this exercise is “gymnasticizing” his entire body.

Step 6
Now we make the grid more visually interesting by raising a cup on one side of each vertical (two holes higher than the lower side), so the jumps are angled in an alternating fashion similar to the football-grid exercise. I canter Alter to it in the same way and then leave him alone to do
his job.

Like the last exercise, this one is great for improving straightness and rhythm while rocking your horse back onto his hind end and making him quicker with his front end. It helps to center his arc correctly over the tops of the fences. It also teaches him to learn from his own mistakes and back himself up from the jumps to avoid going “past the distance” or getting too close to the jump on takeoff. Meanwhile, you can focus on your own position and balance.

Only do this exercise with an experienced horse who is already familiar with bounce jumps.

Set up three small crossrails 9 to 10 feet apart. Alternatively, you can make each jump a single rail, raised at one end and resting on the ground on the other end as you did in Exercise 1. If you and your horse are more experienced, make the jumps small verticals, no higher than 2½ feet. If he has a naturally bigger stride, increase the distances between the jumps to as much as 11 feet. Place a ground rail on each side of every jump. This will help your horse’s depth perception and prevent him from going past the distances.

Approach the bounces in a collected canter, being sure that your horse is in front of your leg. In this exercise, it’s better to be a little tight to the jumps than too forward. When you arrive at the first jump, leave him alone to focus on his job. The more you can stay out of his way, the better. Hold your two-point position throughout the exercise, allowing him to jump up and close your hip angle over each obstacle.

If he gets quick over the bounces, think of being almost a little behind the motion with your body, using your weight—not your hands—to gently slow him down.

Jump the bounces in both directions. When that’s going well, you can gradually add another jump or two.

If you have a young horse and want to trot instead of canter into the exercise, put a placement pole 7 to 8 feet from the first jump to help him arrive at a comfortable takeoff spot. Then set a second placement pole 9 to 10 feet after the last jump. With this setup, jump through the exercise in only one direction so the trot pole is at the beginning, not the end.

Exercise 3: In-and-Out



Setup: Place a vertical and square oxer 21 feet apart with ground rails on both sides of each jump. Add two perpendicular rails on the ground in between the jumps to help keep the horse straight (10 to 11 feet apart from one another initially).

Step 1
We approach the in-and-out at a working canter in the vertical-to-oxer direction first. In the air over the vertical, I follow Alter’s mouth with my hands while focusing my eyes on the oxer.

Step 2
After we land from the vertical, I close my leg and continue to use a soft following hand to encourage him to keep cantering forward. I try to stay out of his way, allowing him to focus on the jumps, not on what I’m doing. As a result, he sets himself up to …

Step 3
… produce a nice round effort over the oxer. Next, we’ll canter the oxer to the vertical.

Step 4
The distance rides tighter this direction, but without any interference from me, Alter studies the problem and sets himself up properly to create an excellent jump out over the vertical, lifting his knees well and powering off his hind end.

This final exercise will continue to emphasize straightness while helping you focus even more on body control and reminding your horse to collect and rock back onto his hindquarters on takeoff.

Set up a small vertical 21 to 22 feet from a small square oxer. Place ground rails on either side of both jumps. Add another pair of ground rails in the middle of the exercise, perpendicular to the jumps, to create a straight chute for your horse to canter through. Some horses spook at these poles when they first see them, so set them 10 to 11 feet apart initially.

Approach this in-and-out at a working canter, starting in the vertical-to-oxer direction. This should ride comfortably at this distance, although you may need to add leg after the vertical to be sure the apex of your horse’s next jumping effort is directly over the center of the oxer.

When your horse has jumped the in-and-out well in that direction, approach it from the other direction. The distance might feel a little tighter this way, so after you close your leg to help him across the oxer, stay quiet in the tack, allowing him to figure out the exercise. Let the jumps back him off. Help him more with your body control than with your hands—by opening your hip angle and sitting a little taller with your upper body.

Continue alternating directions through the exercise a few times to feel how differently you need to ride the vertical-to-oxer versus the oxer-to-vertical. Meanwhile, if your horse is having trouble staying straight, gradually roll the perpendicular ground rails closer together until they are about 8 or 9 feet apart. If he has a major drifting problem, angle these rails into a mild “V” shape, bringing the ends of the poles slightly closer together (but no closer than 3 feet) in front of the takeoff of the second jump. At this point, only jump the in-and-out in this direction—or ask a ground person to reconfigure the “V” each time so that the narrower end is always pointing toward the second jump.

If you’re a more advanced rider and this exercise is going well, practice it without stirrups and/or tie a knot in your reins and put your hands on your hips or out to the sides like airplane wings over the jumps. This will help you improve your independence from your hands and focus on your position and balance in the air.

Remember, your horse’s welfare should always come first. Keep your schooling sessions fun and interesting without ever overdoing it—so you both can look forward to next time!

What to do when your horse has a fever

What to do when your horse has a fever

When your horse’s temperature climbs, it may be best to simply let the process run its course. But sometimes you’ll want to get a veterinarian in right away. Here's what you need to know about fever.

You’ve been keeping tabs on your horse as you’ve gone about your barn chores, but something’s not quite right. Normally, he’s never far from his buddy, and he’d be ranging around his paddock looking for the best bites of grass. Today, however, he’s spent most of his time hanging in the shady corner by himself. He seems normal enough when you bring him in, but as you’re grooming, you get out the thermometer. That’s when you really start to wonder what’s up: His temperature is just topping 102 degrees Fahrenheit.


You know that’s a little high---you’ve been in the habit of checking your horse’s temperature once or twice a month, and it’s always been about 100 degrees---but what do a couple more degrees really mean?

“There are several reasons why horses can have an increased body temperature that would not be a fever,” says Rose Nolen-Walston, DVM, DACVIM, of the University of Pennsylvania. “So the first question to ask when you take a horse’s rectal temperature and it is high is, ‘Is this a fever or not?’”

A “normal” body temperature for individual horses can vary, from about 98 to 101 degrees Fahrenheit, with 100 being average. But it’s also normal for a horse’s body tempera-ture to fluctuate during the day. It may be somewhat higher in the evenings than in the mornings, for example, and it is likely to rise naturally on hotter days or after exercise. A mare’s temperature may rise and fall during different stages of estrus. All of these fluctuations are temporary.

“If you ride your horse and work him hard on a hot day, his temperature rises, but this is called hyperthermia rather than a fever,” says Nolen-Walston. “The main causes of hyperthermia include exercise, extreme heat and humidity, and anhidrosis [an inability to sweat].” Allowing him to rest and drink---and perhaps hosing him down with cool water---ought to bring his temperature down to normal within a half hour or so.

If, however, your horse’s temperature remains elevated with no obvious cause, then it’s time to investigate the reasons why. “Most of the time, if a resting horse has an increased rectal temperature it’s because he has a fever,” says Nolen-Walston.

Rise in body temperature is one of the first and most easily recognized signs of many illnesses, and it is part of the immune system’s defense against infection. “Fever is a response by the body---along with inflammatory processes---to try to combat pathogens by stimulating molecules to speed up healing processes,” says Katherine Wilson, DVM, DACVIM, of the Virginia–Maryland Regional College of Veterinary Medicine.

The best course of action when a horse has a fever can vary. How high his temperature is, and how long it lasts, can help you decide whether it’s best to let a fever run its course---or to call in a veterinarian right away. Here’s a look at how fevers work and how veterinarians suggest you handle them.

How Fever Works

Fever is related to the body’s internal temperature regulation system, which is controlled by the hypothalamus. A small structure at the base of the brain, the hypothalamus receives sensory input from sensors in the central nervous system that monitor the heat of
the blood as it circulates through the brain, as well as from nerves that detect temperatures near the surface of the skin. This gives the hypothalamus information about both internal and external temperatures.

“The hypothalamus determines the body’s temperature set point,” explains Nolen-Walston. That is, the hypothalamus determines the horse’s “normal” body temperature and acts to maintain a consistent internal temperature despite fluctuations in the external world. When the body’s internal temperature deviates too far from normal, the hypothalamus triggers a cascade of involuntary actions to “adjust the thermostat.”

If the horse starts getting too cold, smooth muscles in the skin contract to raise the hairs on his body, trapping an insulating layer of warm air against the skin; muscle contraction also produces vasoconstriction, a narrowing of the blood vessels in the skin, to cut down on the heat escaping into the air. If he remains cold too long, he will begin shivering to generate heat. The hypothalamus might also stimulate the release of adrenaline and other hormones that increase metabolism, effectively causing tissues and organs throughout the horse’s body to “burn hotter,” and prompts behavior changes: The horse seeks shelter. Conversely, if the horse gets too hot, the hypothalamus initiates activities to reduce body temperature. The muscles supporting each hair will relax so his coat lies flat, and the blood vessels widen to facilitate radiation of heat away from the skin. If that’s not enough to cool him down, he will begin sweating.

The process that produces a fever begins when the immune system encounters a pathogen, such as a bacterium or virus. Among the first responders are lymphocytes, which initiate a cascade of biological events. To help neutralize the effects of the pathogens and eliminate them from the body, these cells release large number of cytokines, blood-borne protein messengers that affect the behaviors of other cells. Many of these cytokines have a pro-inflammatory effect---they stimulate all of the familiar signs of inflammation: localized heat, pain, swelling and redness. One type of cytokine, called a pyrogen, circulates in the blood and is detected by the hypothalamus, which responds by raising the body’s “set point” to a higher temperature. “Fever is one aspect of inflammation,” says Wilson. “We think of inflammation as redness, heat, pain and swelling---and fever is often a part of that.”

The raising of the body’s temperature set point is what distinguishes a true fever from other forms of overheating. “If there is something wrong in the body, like an infection, the body produces chemicals that change that temperature set point and make it higher for a while, and this is a fever,” says Nolen-Walston. “In other situations the body simply becomes hotter but the brain set point hasn’t changed.”

When the set point is raised, the hypothalamus stimulates the body to heat itself just as it would if it were in a cold environment. Vasoconstriction traps heat in the interior of the body, while the metabolic rate goes up. Eventually, the horse might start to shiver
to generate more internal heat, even on a warm day.

If a fever starts getting too high, the hypothalamus may abruptly switch to cooling mode: “The second stage of fever involves sweating and panting, and dilation of blood vessels at the skin surface to route more blood to the skin for cooling---making the skin feel hot,” says Wilson. “The horse is breathing hard to try to get rid of the extra heat via the respiratory system.”

How a rise in body temperature helps fight off infection isn’t entirely understood. “There is a lot of debate in human and veterinary medicine regarding the benefits of fever,” Wilson says. “It may improve healing by speeding up chemical reactions in the body and improving inflammatory reactions to foreign invaders.” The extra heat may also inhibit the activities of temperature-sensitive viruses and bacteria. “We think the higher temperature increases the horse’s metabolism and thus the ability to fight off infections,” says Nolen-Walston.

What we do know is that, as the infection wanes, the immune response eases, the levels of pyrogens in the bloodstream drop, and the body’s temperature set point will return to normal.

A Mild Fever

You might suspect something is wrong if your horse acts a bit dull and goes off his feed. But the only way to be certain that he has a fever is to take his temperature (see “How to Take a Horse’s Temperature,” page 29). You also need to know your horse’s normal temperature to interpret the results. A thermometer reading of 100 might be normal for most horses, but if your horse’s temperature is usually closer to 98, then 100 might be a mild fever.

A slightly elevated temperature---just two or three degrees higher than normal---that lasts only a day or two does no harm and is not usually a cause for concern. Your horse may simply be fighting off some mild infection you might never have noticed. If he was vaccinated recently, a slight fever might be just a side effect of building his immunity. If all you notice is a fever of less than two or three degrees and a slight dullness, you might just let your horse rest and check his temperature periodically for the next day or two. Because fever is an active part of the immune system’s function, you might actually prolong the illness if you give the horse medication to bring it down. Consider calling your veterinarian, however, if the fever persists for several days or if the horse begins showing other signs of illness.

“Most of the time we get called out for some other reason, rather than a fever. There are usually other important signs of disease that are noticed first, such as the horse has stopped eating or is breathing hard, rather than the fact that the horse has an elevated temperature,” says Wilson. “Some people, however, do take their horse’s temperature every day and may notice the fever before the horse is showing other signs of illness. I recommend doing this, because the horse’s temperature is good information to tell the veterinarian before he/she comes out to look at the horse.”

When faced with a horse with a mild fever but few if any other signs of illness, a veterinarian will first try to identify the cause. “A good history of the horse through the past day or days can be helpful. Was the horse coughing, or was there a change of diet or any evidence of diarrhea? Was there exposure to other horses that may have been sick? Did the horse have some kind of injury or serious wounds? All of these things might direct us to a diagnosis and the cause of the fever,” says Wilson.

“Then we usually try to determine which body system might have an infection, causing the fever. We listen to the lungs, check for diarrhea, look at the gums, etc.,” she adds. “Probably the biggest thing that helps us in diagnosis, however, is to run bloodwork on the horse. A complete blood count will help us know the degree of inflammation. Changes in white blood cell counts usually indicate an active infection, depending on which types of cells are elevated in number. This may help us know whether the infection is viral or bacterial.”

If the general examination yields some clues, the veterinarian can pursue more specific tests. “The ultimate way to diagnose an infectious disease is to test for that specific disease, usually by running some kind of bloodwork,” Wilson says. “The problem, however, is that there is no general screening test; you have to make an educated guess as to what it might be and then test for that particular disease.”

Often, however, the cause of a mild fever is elusive. “If we can identify a specific cause such as a virus or bacteria, we will try to target that disease process with the appropriate treatment,” says Wilson. “Unfortunately, even if we test for all the common things it might be, sometimes the tests all come back negative. The horse still has a fever, and we are scratching our heads as to why.”

If the horse seems generally well apart from an unexplained mild fever, the veterinarian might opt not to treat it. “Fever in itself is usually not a problem in horses,” says Nolen-Walston. “We almost never see brain damage from fever in horses. The important thing for horse owners to remember is that there is usually nothing particularly dangerous about the fever itself.”

The decision to treat the fever will depend on the horse’s general attitude. “Most of the time we treat a fever because the horse feels miserable and won’t eat or drink. Every horse is different regarding whether and when he might not feel good,” says Nolen-Walston. “If your horse’s temperature is 102 or 103 and he is happy---eating and drinking---there is no need to specifically treat the fever.”

A High Fever

A high fever---elevated by three or more degrees---is a more serious warning sign. In addition to dullness, you might see chills/shivering, sweating, increased respiration and pulse rate, fluctuations in skin temperature or reddening of the gums. An acute fever tends to spike high but come down quickly. A persistent high fever could indicate a serious illness. Either way, it’s a good idea to call your veterinarian.

“A few infections tend to cause very high fevers,” says Wilson. “Whenever I see a horse with a fever of 105 or higher, my first thoughts for possible causes would include strangles0, anaplasmosis0 and Potomac0 horse fever and some of the viruses, such as equine0 influenza. Often a viral infection will induce a higher fever than a bacterial infection, but this alone is not a good way to try to diagnose what is wrong with your horse.”

Another cause of high fevers is endotoxemia---a systemic inflammatory condition that develops when toxins released by certain bacteria as they die get into the bloodstream. “Horses are uniquely sensitive to endotoxins that are produced by a molecule that is part of the cell wall of gram-negative bacteria,” says Wilson. “There are a lot of these bacteria inside the horse’s intestine as normal inhabitants. They live and die there and go through their life cycle in the colon. When a horse has colitis0, some of the endotoxin from the bacteria’s dead cell walls may leak through the colon lining into the bloodstream. This causes a very dramatic cytokine response---and fever.” Endotoxemia can also occur if tissues of the lungs or uterus are inflamed.

Usually, a horse with a high fever will show other obvious signs of illness that point toward a specific cause. “If there are swollen lymph0 nodes under the jaw or thick nasal discharge, this would make us suspect strangles. If the horse has a cough or abnormal lung sounds, we will suspect a virus or pneumonia. With Potomac horse fever, we would probably see diarrhea or signs of laminitis,” says Nolen-Walston. “If the horse has a colic in which the intestine is twisted, we may see endotoxemia and high fever along with severe colic pain. Horses with anaplasmosis may have a high fever with no other signs except maybe mild swelling
of the legs.”

With appropriate testing to confirm the diagnosis, a veterinarian will begin treatment for the disease as a whole, which will also ultimately address the fever as well.

Too High To Tolerate

Extremely high fevers---above 106 degrees---or any fever that goes on for too long can eventually take a physiological toll on a horse. The body uses calories and water to maintain the higher temperature, which over time can lead to weight loss and dehydration. Prolonged high temperatures may change the chemical structures of heat-sensitive enzymes, which can affect metabolic functions throughout the horse’s body. What’s more, too high a fever may make a horse’s immune response less effective.

That said, in practice, a veterinarian’s main concern is likely to be the effects a very high fever has on a horse’s willingness to eat and drink. “Rarely do temperatures get high enough for long enough time to actually damage tissues that are crucial for the animal to function,” says Wilson. “The biggest reason we end up treating fever most of the time is because a fever makes the horse feel bad. If the horse feels miserable he won’t eat or drink, and this can lead to secondary problems.”

For that reason, your veterinarian is likely to administer medications specifically to attempt to bring down a very high fever in addition to other treatments for the underlying disease. “The first thing we’d use to treat a fever is a nonsteroidal0 anti-inflammatory drug [NSAID] like flunixin meglumine [Banamine] or phenylbutazone [bute],” says Nolen-Walston. “These will often bring down a fever.”

These drugs do have to be administered with care, as directed, however. “The important thing for horse owners to know is that these drugs do not work any better if given at higher doses than recommended by the veterinarian, and they will actually be harmful,” says Nolen-Walston. She has treated horses who were hospitalized after their owners administered additional medication when the prescribed doses failed to curb the fever. “The owners told me they didn’t have any choice because the fever didn’t come down.
But if the fever doesn’t come down with the proper dose, giving more will be toxic,” she says. “I have seen horses die from too much Banamine
or bute.”

If your horse has been prescribed one of these medications, and his fever does not come down as expected, says Nolen-Walston, “consult your veterinarian to see what the highest safe level is. The important thing to remember is that these drugs are much more toxic when the horse is not eating or drinking. If the horse is feeling miserable and you are giving NSAIDs and he is not getting any better, don’t give these drugs for more than a day without having your veterinarian take a look and give you some more advice.”

If medications alone are not enough to reduce your horse’s fever, your veterinarian might suggest alternate methods of cooling him down. “Often we try to cool the body in some other way, by using fans or cold hosing, to help increase evaporation over the entire body,” says Nolen-Walston. “If the horse is really overheated, we can give cool intravenous fluids. You don’t have to cool the fluid very much, because even at room temperature it will be lower than body temperature.”

Cold hosing and fans can also be used to cool a horse at home, but remember that fever is only one symptom of a bigger issue that needs to be addressed. “If you are trying to bring down a horse’s temperature and cold water hosing isn’t doing the trick, call your veterinarian,” says Nolen-Walston. “Unless he/she tells you to do something else, most of the time you can wait for the veterinarian to arrive. It would be unusual that the horse would be in critical shape just from fever, but you could work at reducing the high temperature.”

As your horse recovers, it’s a good idea to keep tabs on his temperature at least once daily for another week or two. “There are certain specific diseases that cause fever for a day or so and then the temperature will drop back to normal,” says Nolen-Walston. “Then in three or four days the horse will have another fever. You can’t assume that just because the fever went down for one reading that you’re out of the woods.”

A mild fever may leave your horse feeling sluggish for a time, so it’s best to let him have some rest while he recovers. Most of the time though, a fever is just a sign that his immune system is keeping things under control, and your horse will be back to his old self in no time.

How Dressage Horses Benefit from Variety


Courtney King-Dye explains the importance of days off, hack days and regular turnout.

Horses are like people; a weekend off helps them work better. I always give my horses one day off and a hack one day a week. The young ones I often have jump if I feel they like it. Again, like people, sometimes variety makes concentration easier.

Often if my horses are too heavy and can’t work harder to lose weight, or if they need to build more muscle, or, if like Idy [Idocus, her World Cup partner], they just enjoy a hack, I’ll have them be ridden up hills for a session in addition to their work three days a week. Hills are a good additional way to work without challenging the mind.

I also think it’s crucial for a students to ride on their own to make sure they’re independent and not relying on their instructor. My clients who are in full training get four lessons a week. The horse has one hack day, one day off and the client has one day to ride on her own. It’s one thing to be able to do something if you’re told to, and it’s another to recognize a problem on your own. That’s the difference between a good rider and a good trainer.

I also am a big believer in turnout for exercise as well as for chilling out, if horses like it. When I got Mythy [Harmony’s Mythilus, her 2008 Olympic partner] the previous trainer told me not to turn him out. I did anyway, and he just stood by the gate petrified. So he’s one of the few horses I never turned out.

I know turnout can be dangerous, so I do it as safely as possible in a small, not muddy paddock with the horse all booted up. Even with all these precautions in a paddock the size of a postage stamp, Rendezvous (a Grand Prix mare) broke her leg. I know some people aren’t willing to take the risk, and I don’t blame them. But we’re in the sport because we love horses, and turnout is the most similar to their natural environment, so I’m willing to take that risk. It’s hard. Every time I’d turn Idy out, he’d gallop joyfully around. He had a blast showing everyone how fast he could go. I was always terrified, but I’d prefer him to die like that, joyfully gallivanting, than be safe yet miserable in a stall.

Finish Your Round with Flair


Liza Towell Boyd's step-by-step approach to mastering the final stages of your hunter derby course.


The Challenge: Typically, at the end of the handy course, you see the riders come back to the walk promptly after their last fence and walk directly out of the ring. But sometimes the gate is very close and your horse may be too enthusiastic to do this smoothly. Remember that you are being judged from the moment you walk into a ring to the moment you walk out of the ring. I don’t like to see riders do a rough downward transition just trying to achieve the walk in time.


Your Goal: Landing and immediately coming back to the walk is the handiest, and over time this should be your goal. But if your horse is strong and you are going to end up in an unattractive tug of war, it is more appealing to do a tight turn and then walk directly out of the gate. The trick is testing your ability in advance and knowing what you and your horse can execute smoothly.

The Exercise: Set a simple jump on an angle near the gate of your schooling ring. Or set a simple jump heading right toward that gate. Either option works, and you will encounter both set-ups in derby classes. Place a cone about three strides before the gate.

Step 1: Jump the fence quietly and practice coming back to the sitting trot as soon as you can—if it needs to be on a circle, that’s a good place to start. Once your horse gets the idea, practice jumping and then coming back to the sitting trot earlier and earlier until you can do it by or before the cone.

Step 2: Jump the fence, land and then halt and back up a few times. Try to do this earlier and earlier until you can halt quietly by the cone.

Step 3: Now jump the fence and come back to the walk at the cone and walk out of the gate. If your horse is now responsive enough to execute this, that’s your game plan. Note that if you land on the wrong lead and you are worried that you might miss the change, then why take the risk? Just go immediately to the walk.

Step 4: Keep practicing, but if your horse is too anxious to give you the walk in a reasonable time—then plan for a balanced tight turn and then walk out of the gate. Practice this to the right, then eventually move the jump so that you can also practice a tight turn to the left. Over time, your horse should be able to land, execute a nice turn that fades into a walk and exit quietly out of the gate. The beauty is that the turn will put the brake on your eager horse. Your job is to make this transition smooth and make it look like you planned it. Which you did!

Making the Switch to Senior Feeds

Making the Switch to Senior Feeds

When is the best time to begin a specialized feeding regimen for your older horse? These tips can help you determine how to best meet his needs.

Taking care of your horse as he ages means making management changes that reflect his current needs. So when is it time to switch to a senior feed? That depends on many factors. As a general rule, senior feeds usually become appropriate for horses when they reach the age of 15. That said, however, it’s possible that a much younger horse with digestive and nutritional challenges will benefit from senior feed. It’s also possible that a horse can coast into his 20s without needing a specialized feed. Horses, like people, show the effects of age at different rates, so here are few questions to ask to help you determine when it might be time to switch your horse to a senior feed:


How are his teeth? Aging horses often have worn down or missing teeth, making chewing more difficult and less efficient. Younger horses with unusual dental issues can face the same challenges. Senior feeds are typically processed to make them easier to chew, and a “complete” senior feed can take the place of hay if a horse is unable to eat his daily roughage in flake form anymore.

How is his digestion? Take a closer look at your horse’s manure. If you see forage pieces of more than an inch long, your horse may not be digesting his feed efficiently. This is a normal development in an aging gastrointestinal system, but one that is easily addressed with a senior feed formulated for easier digestion.

How is his “fuel efficiency?” A horse who is no longer maintaining his weight or energy levels on his usual feed may be ready for a senior formulation. Even before weight loss is apparent, a horse may lose his “bloom” if he is no longer able to utilize his current ration efficiently. Loss of body condition can be due to many factors, however, so you’ll want to call your veterinarian to rule out illness or other problems before deciding to try a new feed.

Rules of the Ring: Universal Dressage Ring Etiquette

Rules of the Ring: Universal Dressage Ring Etiquette

Beth Beukema shares 12 rules to help riders determine who has the right of way in a crowded arena.

The rules of ring etiquette are flexible and adaptable to the given situation. While riding, the safety of horse and rider should always be the first priority and common courtesy should also be present. When riding in a group, remember to communicate with other riders and keep an eye on patterns and attitudes of the horses around you. However, here are a few standard rules that should help.


Right-of-Way Rules

1. In general, riders should pass left shoulder to left shoulder.

2. Remain on the second track when working at the walk.

3. Announce, in a loud voice, when you are entering and exiting the arena.

4. Keep at least one horse’s length between you and another horse.

5. Don’t ride up the tail of any horse. Turn across the arena.

6. Use the second and third tracks. The most used part of the ring is the track—the outermost path around the ring going in to each corner. When many horses are utilizing the same space, it may be necessary to use the second and third tracks. The second track is just to the inside of the outer track, leaving just enough space to pass between you and the rail. The third track is two meters (6 ½ feet) from the rail and allows even more room for horses to safely pass you on the outside.

7. When riding a circle, look in the direction you are going and ride on the second track. This allows other riders to pass you on the outside and not cut through your circle. If you doubt that another rider is aware you are circling, you may call out “circle,” to let others know your intentions before moving to the second or third track.

8. Faster horses or horses traveling at a faster gait should avoid getting too close behind other horses. This can be achieved by circling or utilizing ring figures such as a half-diagonal, serpentine or turning across the B-E line.

9. In a lesson situation, the person under instruction should have the right-of-way. Other riders in the arena can be listening to the instructor and anticipating where the horse and rider in the lesson will be going next.

10. Green horses and beginner riders should be given more space by more experienced riders, who also should keep an eye out for the possible out-of-control moments that green horses and riders may experience.

11. Upper-level horses can be intimidating to a lower-level rider as they come across the diagonals. However, the basic patterns they follow are the same as at the lower levels. They should be treated as any horse and rider would be. By making eye contact, you can avoid potential collisions.

12. The use of voice is another tool to gain the attention of focused riders and to let them know where you are planning to go.

These rules are a good starting point for approaching a ring full of horses. However, there are many situations that call for deviations from the basic rules. If a 3-year-old horse has an explosive moment and comes leaping across the diagonal while you are pleasantly trying to leg yield on a line that has now turned into a collision course with a spring-loaded youngster, you need to stay out of the way. Riding requires tact, timing and coordination with your horse as well as the other riders in the arena.
