A dog collar may be a piece of material put around the neck of a dog. A collar is also used for restraint, identification, fashion, or protection. Identification tags and medical information are typically placed on dog collars. Collars are often employed in conjunction with a leash for restraining a dog. A better alternative to a dog collar may be a dog harness, as collars are purely around the neck, during a dog restrained in a collar to have severe pressure placed on its trachea once it pulls, and slip out easier if it is too loose, yet collars are still the more common kind of directing dogs.
