A padded band around the nose adds extra comfort for your pet. 2. This pet muzzle is suitable for Chihuahuas, Yorkshire Terriers, etc. However, it is not suitable for dogs with short noses, such as Pit Bulls and Boxers. 3. Our soft muzzle features a durable and adjustable nylon strap that easily ensures a comfortable environment for your dog. The contoured slide buckle makes putting on and taking off the muzzle quick and easy. The open-mouth design protects your dog from chafing. 4. If used properly, this humane muzzle can help prevent dogs from biting, destroying, fighting and digging holes. Because it is quite lightweight and portable, it is the choice for going out, walking your dog, muzzle training, vet visits, haircuts, nail trims, etc. 5. To better fit your dog, please measure twice before purchasing. When you receive your muzzle, make sure it is large enough to allow your dog to pant and secure when worn. If this is your dog's first time wearing a dog muzzle, please introduce your dog to the muzzle with more treats and they will be more receptive.
