Is your dog reactive? Does he react to dogs, people or noises by trying to bark or bite? Muzzles are safety training tools for keeping control of your dog on visits to the vet, groomer, or places that can be scary or overwhelming for your dog. Safely prevents dogs from nipping, biting, and barking while still allowing them to pant. Extra padding keeps your dog comfortable and the fully adjustable snout and neck strap allow for a perfect fit.
