Prognathism

Filed Under: Dogs, General Care

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. An undershot jaw is also considered to be normal conformation in the Persian cat.

Prognathism may cause difficulty in eating and retrieving, producing excessive wear and tear on the teeth as well as lesions on the lips and gums due to the abnormal placement of the teeth. Removal of the teeth may be necessary under extreme circumstances.

The alteration of blood flow leads to the breakdown and degeneration of the union between the horny and sensitive laminae of the hoof.
