The Tough 1 Easy Breathe Grazing Muzzle is a great tool to help with weight management for the easy keeper! This halter has a built-in muzzle to provide a comfortable way to limit your horse's intake of grass and hay without obstructing his ability to drink or breathe. The 1” opening reduces the amount of grass and hay that your horse eats while the larger holes in the front allow for easy, comfortable breathing. Finally, it is fully adjustable for a great fit, has a breakaway feature for optimal safety, and neoprene lining to keep your horse comfortable.
