Horse anatomy
Muzzle
The nose and mouth area. Helps the horse breathe, smell, and eat.
A closer look
The muzzle is the lower front of the horse's face, including the nostrils, lips, and chin, and it is one of the most sensitive parts of the horse. Its skin is thin and covered with fine hair and long whiskers, and the upper lip is flexible enough to sort through food and pick up small pieces. Horses with white face markings often have pink skin on the muzzle.
Why it matters
Horses explore the world with their muzzles, a bit like we use our hands. Because a horse can't see the area right under its nose, it relies on its lips and whiskers to feel what is there, which is why fingers near the mouth can get nipped by mistake.
