“Tying-Up” In Horses- Everything You Need To Know

Have you ever heard tying up in horses, and have no idea what they were talking about? Or maybe you thought they were actually talking about tying their horse up to something!

Don’t worry, you’re not alone! The phrase “tying up” actually references a few different syndromes in sport horses. These syndromes result in the horse’s muscles “tying up” or almost locking in place.

While tying up is not a new problem, lots of new research has been conducted and is still being conducted by vets to help understand what causes it and what can be done to help it.  In this article, I’ll be discussing what happens when a horse ties up, why horses may tie-up, what to do when your horse ties up, and what you can do to prevent your horse from tying up.

What is Tying-Up in Horses?

Tying up is technically called “exertional rhabdomyolysis.” The American Association of Equine Practitioners describes tying up in the following words: “…what was considered by some early researchers to be a problem that had one basic cause, e.g. lactic acid, is actually a broad-scale syndrome that will require continued research on a variety of fronts before every aspect is understood. In other words, tying-up is not one disease, but several different diseases that have similar signs and different causes. Therefore, the management of a Thoroughbred that suffers from tying-up would differ from the management of a Quarter Horse that is tying-up, would differ from the management of a backyard pleasure horse that has the same symptoms.” 

They also list some typical symptoms of tying up to be sweating, stiffness, and reluctance to any kind of activity.  Other symptoms include increased heart rate, pawing, and sometimes bulging muscles.

Have you ever had a muscle lock up when you’re at the gym, or when you’re riding? Or had terrible lactic acid after a really hard workout, and it seems more painful just to move? These are similar to what horses feel when they are tying up.

There are loosely two types of tying up: sporadic and chronic.  Sporadic tying up is when a horse might tie up from time to time due to excessive levels of exercise or lack of electrolytes.  In contrast, chronic typing up is when a horse ties up regularly, and it isn’t necessarily triggered by a common condition.

Treatment and prevention look different for every horse, but especially between horses that experience sporadic and chronic tying up.

Why Does it Happen?

The reasons for tying up also depend on what type of tying up a horse is experiencing.  If a horse has sporadic tying up, the cause for the tying up can typically be traced back to one or two things.  

Tying Up in Horses - Why Does it Happen

Depending on the horse, these things can include excessive exercise (over the amount that the horse is accustomed to), lack of electrolytes (think Gatorade), heat exhaustion, fatigue, extreme nervousness, dehydration, mineral deficiencies, and hormone imbalances. 

Alternatively, if a horse has chronic tying up, the cause for tying up is unfortunately as simple as genetic inheritance.  Sometimes horses with chronic tying up can be triggered by certain circumstances, such as overwork, but it is common for them to also tie-up with no trigger or reasoning.

What Can I Do When it Happens?

Once your horse starts tying up, unfortunately, there’s not much that can be done besides waiting for it to pass.  If your horse starts showing symptoms of tying up during training, stop all training and exercise immediately.

Make sure your horse is in a safe environment where he won’t be likely to hurt himself, and call your vet.  Offer your horse water, preferably water that has added electrolytes.  Try to keep your horse calm and as comfortable as possible.  

If your horse has a stall, his stall will likely be where he is most comfortable. You can also run a hot or cold (depending on the season) wet sponge over the affected muscles if you think this will help your horse relax.

If your horse has been known to tie up in the past, then the diagnosis should be easy.  But, if this is new for your horse, there are lots of different things your vet will probably want to do.  According to SmartPak, some of these things could include “…physical examination, bloodwork, muscle biopsy, and possibly other tests.”

What Can I Do to Prevent Tying Up in Horses?

While there isn’t much you can do to help your horse after he starts tying up, there are plenty of things that you can do to prevent him from tying up in the first place.  As always, every horse is different and will respond differently to each method.

One popular way to help with tying up is through dietary changes. Restricting a horse to certain types of grain or feeding a horse certain supplements may help. Hygain Feeds produces its Hygain Release product specifically to help horses that tie up!

They say that horses that tie-up should be on a very small amount of grain, good quality hay, calming supplements, and a good balance of electrolytes.  They also say that if the specialized grain is not an option, the grain with the lowest sugar and starch levels will be best.

The famous supplement manufacturer, SmartPak, also has some dietary recommendations.  They recommend that horses inclined to tie up should be on a Chromium or Magnesium supplement, or some supplement that includes a mix of the two. 

Tying-Up In Horses- Preventing

Vets will sometimes prescribe anti-inflammatory medications, such as bute (Phenylbutazone), for horses that have had a severe case of tying up.

Outside of these things, you need to make sure your horse is experiencing as little stress as possible.  Make sure he is getting lots of turnouts, make sure his turnout situation or stalling situation doesn’t give him any stress or anxiety and make sure he always has access to water and always has something to snack on (typically hay). 

The best advice I can give you is to know your horseKnow what stresses your horse out, and do your best to prevent these things from happening.

Conclusion

Tying up can be scary, especially if it is your horse’s first time.  And, it can be scary because there is no one specific cure. But, it can be treated.  Every horse is different, and every horse will react to treatments differently.

But, there are things you can do to help.  I hope this article helped you learn more about tying up in horses.  If so, please share this article, and share with us your experience with horses tying up!
