To prevent esophageal obstruction, take a page from the scientific journals

Derby, your 15-year-old Thoroughbred, hasn’t finished his grain. A greenish nasal discharge and a large amount of saliva stream from his mouth. He also keeps extending his neck and coughing repeatedly, as if he’s trying to clear his throat. What’s going on here? 

Choke, or esophageal obstruction, occurs when food or foreign materials partially or completely block the esophagus. Choke might not be immediately life-threatening—he can still breathe—but it is distressing, will prevent your horse or pony from eating and drinking, and must be addressed by a veterinarian as soon as possible.
