The present invention provides a bite prevention implement with which, when trimming a dog's hair at a pet grooming parlor or providing medical treatment to a dog at a veterinary hospital, it is possible to safely restrain the dog in place with less stress for both human and dog without placing a burden on the dog. The bite prevention implement according to the present invention is a towel-like fabric that is wide enough to cover the entire lower jaw of a dog and long enough to cover the entire head except for the nose. The dog's jaw is placed in the center of said towel-like fabric, and then the fabric is wrapped around the back of the head so as to restrain the jaw joint in place. The width of the towel-like fabric is adjusted by a pair of covers and a string. Both ends of the towel-like fabric have an extension belt attached thereto so as to have the belt connected on both sides for holding a region from the back of the head to the neck. Further, the center of the towel-like fabric has attached thereto a hook-and-loop fastener, a string, and a hook, all of which function to restrain the jaw in position. The towel-like fabric has a pad added to the top end thereof, and is configured in such a manner as to allow the nose to be exposed out of the fabric.
