American Pit Bull Terrier Standard

Recognized by the AMA in 2017

Background: The American Pit Bull Terrier was developed in the early 1800’s as a result of crosses between the renaissance period bulldogs of that time and game terriers. The renaissance period Bulldog which, when crossed with game terriers, produced the first "Bull and Terriers". The renaissance period Bulldog was a fierce, courageous animal used in the sport of bull-baiting. When the sport fell from public favor and was outlawed, their supporters turned to dog fighting and sought to create a sporting dog that, while retaining the legendary courage and ferocity of the Bulldog, would incorporate the greater agility of the terrier. The extraordinary vitality of this breed is a direct result of breeding for successful fighting dogs. Immigrants brought these bull and terrier crosses to the United States. This type of dog was instrumental in the success of farmers and settlers who developed this country. They were used for general farm work, hunting wild pigs, bears, and other large game, guarding the homestead, and general companionship. The American Pitbull Terrier of today excel in many various performance and working venues as well as conformation and as family companions.

Any fault, which is extreme, should be considered a serious fault and should be penalized appropriately.
