THE MUZZLE EVERYONE'S BEEN ASKING FOR!!! The Grazing Muzzle is recommended and used by many veterinarians to prevent problems caused by overeating, and the variety of health concerns obese donkeys have. The Grazing Muzzle was designed to reduce the amount of grass your donkey can eat while grazing. The durable urethane bottom has a one-inch opening that allows your donkey to eat only small amounts-just enough to keep him/her from becoming frustrated or bored. Drinking is unrestricted. Can be used as a breeding muzzle on jacks and on jennets during foal rejection.
