The Canine Friendly Short Snout Muzzle is made from breathable mesh and a durable nylon construction. Designed for short snouted canines that cannot fit a traditional muzzle. It features an adjustable slider and easy to use side release buckle that make muzzling quick and convenient. The soft bumper on the top of the muzzles prevents the mesh from rubbing the eyes. The soft fit muzzle is the perfect addition to any pet first aid kit. Designed as a temporary restraint only. Never leave a muzzled dog unattended as prolonged use or improperly fitted muzzles can affect a dog's natural ability to cool itself. Size Small fits an end of snout circumference between 9-12 Inch.
