The Groom Professional Comfy Short Nose Mesh Muzzle is perfect for breeds who don't have a long snout, meaning they cannot use traditional muzzles. This top quality muzzle is manufactured using breathable mesh and a durable nylon. It features an adjustable slider for length on the face and an easy to use side release buckle to make muzzling quick and convenient. The soft padding across the top of the muzzle help to prevent rubbing on the face. The soft fit muzzle is the perfect addition to any pet first aid kit or in the salon for emergencies! Never leave a muzzled pet unattended or use during strenuous activity. See the size guide. Head circumference of the size medium is 28-43cm.
