A dog collar is a piece of material put around the neck of a dog. A collar may be used for control, identification, fashion, or other purposes. Identification tags and medical information are often placed on dog collars. Collars are also useful for controlling a dog manually, as they provide a handle for grabbing.
The thick leather weave lets the dog pant and breathe, but prevents her from biting you or other dogs. Wire basket muzzles are made of wire formed into a basket around the nose and mouth of the dog, usually with a leather strap that holds the muzzle around his nose and a strap behind the ears. This type is the best choice if your dog will be wearing a muzzle for a long time or will be unsupervised.
