The Best Friend Standard Grazing Muzzle attaches to your own leather or breakaway halter with four adjustable hook-and-loop straps. To attach, loop the four straps over the noseband and chinstrap. (The two side straps may be looped through the halter rings for added stability.) Leave the metal rings in the down position to allow the muzzle to breakaway. To disable the breakaway feature, slide the metal rings up (see photo) over the hook-and-loop straps.
