Best Friend® Deluxe Grazing Muzzles are 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. Rather than being restricted to a non-grass environment to control intake, horses are free to exercise and socialize as part of the herd. A combination grazing muzzle and breakaway halter all in one, the design utilizes plastic side-release buckles as its breakaway feature. Each Deluxe muzzle comes with a spare buckle that can be easily attached in the field.
