A grazing muzzle is often recommended by equine health professionals to prevent, as well as treat, laminitis, founder, obesity, colic and other diet-related diseases. The Best Friend Deluxe Grazing Muzzle is one of the top rated grazing muzzles due to the design and durability. The small opening in the bottom allows horses a limited amount of grass, yet unlimited water. Reinforced rubber bottom and straps. All-in-one design. The halter fits many size horses but is not required. Six fully adjustable sizes for a good fit and minimal rubbing. There is a breakaway feature for safety during turnout. Extra plastic buckle included.
