This is our most comfortable muzzle. This is the safest muzzle in the world & works so well, we had to patent its design. It allows your dog to breathe normally while at the same time restricting aggressive behavior. Looks great, most importantly it feels great for your pet. Used by professional groomers, trainers & pet owners. Durable design makes it difficult for pets to pull off, this is an easy to clean with wipes. Washing is not recommended.
