Shires Comfort Grazing Muzzle. Shires grazing muzzles are proven to help with controlled or restricted feeding regimes and special diets. The Comfort Grazing Muzzles are cut back under the chin to avoid unnecessary pressure and improve the fit. The muzzle features a rubber base with a hole in the bottom through which grass can enter, reinforced nylon web bars which allow free air exchange and the anti-chafe padding around the inside of the muzzle protects the delicate nose and chin. The head and throat straps benefit from anti-chafe padding and the fully adjustable harness is fitted with a field safe fastening. The D-ring allows a leadrope to be attached. Colour: Black.
