The Beeztees Muzzle ensures maximum safety, without taking away your dog's comfort. A muzzle is useful if your dog exhibits inappropriate or aggressive behavior towards other dogs or people, eats food from the street, or to make sure your dog doesn't lick his or her wounds. This muzzle has been developed in such a way that your dog can still eat and drink or pant. The difference with other muzzles is that you can still reward your dog in the form of food. This is very useful when your dog wears the muzzle during behavior correction. – Secure bracket that can be attached to your dog's regular collar – Soft neoprene protective layer provides extra comfort. – Available 6 different sizes Sizes for dog breeds: – 1: Border Tierrier, Jack Russel Terrier – 2: Cocker Spaniel, Beagles – 3: Collie, Staffordshire Bull Terrier – 4: Pointer, Pit Bull – 5: Labrador, German Shepherd – 6: Great Dane, Rottweiler
