bulldog

Does your dog have a marked protrusion of the jaw or mandible? Then your dog is considered to be prognathic. Common names for this condition include undershot or monkey jaw. This trait is a fault in many breeds where a scissor bite is the breed standard, and alternatively, it is a desirable characteristic in many brachycephalic breeds (short-faced, wide-headed breeds) such as the English Bulldog and the Pekinese.
