Horses’ ears are by far the most expressive part of their bod in terms of communication. There are at least seven ear-positions that can tell you what a horse is thinking and feeling. The chart below shows these positions.
An action that often scares people new to horses is stomping. Horses lift and stomp their hooves quickly on the ground. The most common reason for this action is flies. Horses use the stomping motion to get rid of flies that bite at their legs.
My favorite body language position that horses show is the drooping lip. When a horse’s bottom lip is limp and drooping down from his muzzle, this is a sign that he is completely relaxed and trusting of his situation.
