Choke is the most common esophageal disease in horses. It is a passenger disorder that can be partial or complete. Most often, choke is caused by too large and too hastily gulped down pieces of food.
You can recognize a choke when your horse runs food mash out of the nose. Sometimes you can also recognize the blockage as a bulge on the left side of the neck.
First of all, you should contact the veterinarian and try to keep your horse’s head low. Your horse should not be eating food or drinking water. It is important that you do not try to massage the blockage back up towards the head!
