An all-in-one design that does not require a halter and uses a breakaway plastic buckle in the headstall for safety. Recommended by equine health professionals to prevent as well as treat laminitis, founder, obesity, colic, and other diet related diseases. The small opening in the bottom allows horses a limited amount of grass, yet unlimited water. Allows horses to be free to exercise and socialize as part of the herd. Tips for first time muzzle users: The grazing muzzle should fit loosely. Allow 1″ between the bottom of the grazing muzzle and the horse’s face. Introduce the grazing muzzle gradually. Place a treat such as a carrot inside before placing the grazing muzzle over the horse’s face. Don’t put the strap over the horse’s head the first time he places his face inside the grazing muzzle. If necessary, place a small amount of grain or other treat on the ground to stimulate grazing behavior.
