Don’t Choke!

While choking in humans can be a very violent, noisy affair, choke in horses can present in a very different way.

By Sarah E Coleman

What horses are at risk?

The main cause of choke in horses is a lump of poorly chewed food, though horses can choke on non-food items, as well. These objects are typically rocks or some other item a horse samples, or could be wood if a horse is a cribber.

 Horses that bolt their feed are more at risk for choke than horses that eat more slowly, as they eat as much food as they possibly can as quickly as possible. Additionally, older horses that have bad (or no) teeth are also at higher risk for choke as they have a harder time chewing their food properly.

Horses that eat specific types of feed can also be predisposed to choke: pelleted feeds, in particular, can cause a horse to choke as they are compressed during the processing of the feed, then expand when exposed to moisture, like saliva. 

How to diagnose choke

While not all chokes present the same way, some indications that your horse may be choking include:

  • Standing with his neck held straight out and down
  • Repeatedly trying to swallow (the horse might seem like he is gagging)
  • Drooling
  • Saliva and/or food or grass coming out of the horse’s nose
  • Coughing

How choke is handled

No matter what, choke is a veterinary emergency. While you’re waiting for your vet, if you’re comfortable doing so, you can sedate your horse to try to get him to relax. Sometimes the sedation alone will allow your horse to relax enough that the mass will pass. Once your vet arrives, she will administer anti-spasmodic medicine to try to get his esophageal muscles to relax. If this does not work, she will pass a tube through your horse’s nose until it hits the obstruction. She will them pour warm water into the tube and empty it repeatedly as she tries to gently push down the mass. The goal is to soften the mass with enough liquid to allow it to pass into the stomach. If your vet is unable to get the mass to pass manually, your horse may need surgical removal of the obstruction.

Once your vet gets the mass to pass, which may take quite a bit of time, you will most likely be advised to not let the horse eat for 24 hours. This time allows the throat to rest and begin healing from the trauma of the lodged mass. Once your horse can eat again, he will most likely need to eat food that has been softened with water before transitioning back to dry food in a few days.

Your vet will administer pain medications to your horse to alleviate the inflammation from where your horse had the obstruction. Choking horses are also at risk of developing pneumonia, so your vet may opt to place your horse on a round of broad-spectrum antibiotics. 

Reasons why horses choke

Horses can choke for a variety of reasons, but some of the most common are:
  • Anxious about grain meals (there are also many causes of this, but it could be related to having had food withheld from him in the past, being low in the pecking order, etc.)
  • Not enough saliva
  • Poor dentition
  • Complications from EPM (where muscles surrounding the larynx may not work as well and allow food to get trapped
  • Injury to the esophagus (either from trauma or a tumor)

How to prevent choke

There are certain things that can be done to prevent choke. These include:

  • Getting your horse’s teeth checks at least twice a year, more if he is older or having issues
  • Feeding a non-pelletized feed
  • Using a slow feeder for grain meals or drop some large, smooth stones in his bucket if he bolts his feed
  • Adding water to his meals to make them more moist
  • Feeding more grain meals so he is not as anxious to bolt feed
  • Feeding hay first so he is not as hungry when his grain comes
  • Separating him to eat if he is fed in a herd and bolts his feed
  • Having water available to him when he eats grain meals
