In horses, choke is a condition that occurs when food or some other material becomes stuck in the esophagus. The term choke can be a bit confusing since in people, choking can refer to having something lodged in the trachea (airway).
A few reasons this occurs are because the horse is not chewing properly or the horse is eating too quickly.
What are signs of choke?
Discharge (sometimes containing feed material) coming from both nostrils and/or mouth.
Some horses may make repeated, unsuccessful attempts to swallow.
Not wanting to eat or drink
