What to do when your horse ties up

If your horse develops severe muscle cramping, call your veterinarian, then keep him still and comfortable until help arrives.


Bringing a horse back into condition after some time off must be done carefully: He needs to work up a sweat to gain fitness, but too much exertion increases the risk of several serious complications, including tying up.

Tying up, technically called exertional rhabdomyolysis, refers to severe cramping of the large muscles of the hindquarters, back and, sometimes, the shoulders during or after exercise. In some cases, damaged or dying muscle cells can release enough toxic debris into the bloodstream to stress the kidneys. Extreme cases may be fatal.

Repeated tying up occurs in horses with two specific disorders characterized by cellular dysfunctions in the muscles: polysaccharide storage myopathy (PSSM) and recurrent exertional rhabdomyolysis (RER). However, heat stress and/or electrolyte imbalances can cause virtually any horse who exerts himself to tie up under the right conditions. Here’s what to do.

CALL YOUR VETERINARIAN IF
  • Your horse comes to an abrupt halt with massive muscle cramping, usually over the hindquarters. Or if he stiffens up and moves forward only reluctantly, perhaps taking only short strides and stabbing his hind toes into the ground.
  • He sweats profusely, with less sweat over the affected muscles.
  • He has a pained, “colicky” look, with rapid breathing and a fast heart rate.
  • He develops muscle tremors.
  • His urine is discolored---from a reddish tinge to a dark, coffee-like hue.


AS YOU WAIT FOR YOUR VETERINARIAN
  • Keep the horse still. Your horse cannot “walk off” these cramps, and forcing him to move may cause further injury to his muscles. Keep him standing right where he is until your veterinarian arrives. If you must move the horse for safety or to get treatment, bring a trailer to him and move him only the minimum number of steps.
  • Encourage him to stay calm. Keep a buddy with him or offer him small bites of hay. Stress can make this condition worse, so do what you can to make the environment soothing.
  • Offer water, possibly with electrolytes. Water with dissolved electrolytes may be helpful, if your horse will drink it. If he won’t, offer him plain water, too.
  • Warm up or cool down the affected muscles, according to the season. If it’s a hot summer day, sponge cool water over your horse. (Contrary to the old myth, splashing cold water on hot muscles will not cause further cramping.) In cold weather, place a blanket over your horse’s hindquarters to warm him up.
  • Watch for urination. The color of the urine will offer important diagnostic information for your veterinarian. If your horse urinates while you’re waiting for her to arrive, take note of the color or, better yet, catch some in a clean, empty container.
  • Monitor your horse for other complications. The metabolic imbalances associated with fatigue can lead to other issues as well. Synchronous diaphragmatic flutter, called “thumps,” is one possibility---look for a distinctive jerking, or tic, in your horse’s flank that matches the rhythm of his heartbeat. Hyperthermia (overheating) can develop when a horse can no longer cool himself by sweating---look for agitation, panting through the mouth, excessive sweating and skin that is noticeably hot to the touch. Dark mucous membranes and skin that does not snap back into place after being pinched are signs of serious dehydration. A horse who is exhausting his fluid reserves may develop anhidrosis, the loss of the ability to sweat. If you notice any of these other signs starting to develop, call your veterinarian with an update; she may decide your case is becoming critical.

The Secret to Following Your Horse’s Motion

Liz Steacie shares advice to help riders find a better sitting trot. Plus, try her unmounted exercise to get a better feel.


Learning to sit the trot effectively and to appear relaxed and in harmony with the horse is perhaps one of the biggest challenges in the world of dressage. Many of today’s dressage horses have big, bouncy trots that can be daunting for even experienced riders with supple seats. It is, however, very important that every rider develop her ability to sit the trot in order to influence the horse effectively during the trot work. So think of sitting trot as proactive rather than reactive.

The first step a rider must accomplish is the correct position in the saddle. You want a tall, correctly aligned body position, a supple waist and strong abdominal muscles. The upper body must be very straight and placed directly over the hips. A viewer should be able to draw a straight line from the rider’s ear through the shoulder and hip to the heel, and that line should be exactly perpendicular to the ground.

The pelvis should be centered in the deepest part of the saddle and balanced between the two seat bones and the pubic bone. (If too much weight is placed on the seat bones, the rider will be behind the motion and behind the vertical with her upper body; if too much weight is placed on the pubic bone, the rider will be perched on her crotch and tipped forward.) Sit as tall as possible. While lightly balanced on the seat bones and pubic bone. Your back should be close to flat and your head carried over nicely squared shoulders and a raised an open chest.

Once the seat is balanced, the rider needs to open the angle between the hip and thigh allowing the legs to drop down almost vertically from the hip. It is the open angle between the hip and thigh that will enable the rider to use her hips to influence the trot. This open angle also will lead to the softly draped long leg that is advantageous in many ways. In this position, the rider is correctly balanced and properly aligned to ride the sitting trot.

To ride the sitting trot, the rider must make her waist supple—not loose and floppy, but elastic and supple. The very slight pelvic motion involves pushing the pelvis down and toward the hands through relaxation of the waist and abdominal muscles. The timing of the motion is critical—the rider must straighten as the horse begins the stride and then push down and slightly forward just before the completion of the stride. In this way, you can “bounce” the next stride with your seat, just by allowing yourself to relax down into the saddle.

You can get the feeling of the pelvic motion while dismounted: Stand against a straight wall with your heels, hips and shoulders touching the wall, and your knees slightly bent. Place your hands over your tummy, just below your navel. Using your abdominal muscles, push your back toward the wall—this is the “straightening” phase of the sitting trot. Relax your abdominal muscles toward your hands and allow your back to fall away from the wall—this is the relaxing or “pushing down” phase of the sitting trot. At no time should you grind your seat bones into the saddle to try to sit more “into” the horse—this is uncomfortable for the horse and counter productive.

Once a rider has the timing and strength to follow the motion of the gait, she will be able to change the trot strides wit just a little more emphasis on the pelvic motion—straighter and taller for a shorter, bouncier stride and more down and forward for lengthening the stride. Influencing the trot involves “riding the stride,” rather than going with the motion. The rider must be balanced and poised in the saddle and able to anticipate the stride. When this is done correctly, she is very slightly ahead of the motion of the trot, and by being slightly ahead, has a good opportunity to influence the size and shape of the next stride. So, rather than following the motion of the trot, a rider can lead the motion of the trot, thereby staying in balance and harmony with the horse.
