The American Bully breed was developed in the mid-1990s by breeders on both the East and West coasts of the United States. They used, as their foundation stock, United Kennel Club (UKC) and American Dog Breeders (ADBA) registered American Pit Bull Terriers mated with American Kennel Club (AKC) registered American Staffordshire Terriers; different varieties of the same breed based on bloodline history. These dogs were first known as “bully type” American Pit Bull Terriers. For the past 25 years, these dogs have been bred, bloodlines refined, and promoted across the U.S and overseas. The breeders of these dogs have developed this breed for a specific build and temperament so unique that they have been recognized as a breed separate from the American Pit Bull Terrier. These dogs were first registered as the American Bully with their own kennel club in 2004. Recent speculation that the breed was influenced by the blending of other bully breeds into their gene pool prompted the UKC to recognize the American Bully as a separate breed on July 15, 2013. Beginning in March 2015, dogs exhibiting these physical characteristics unique to the American Bully breed, or being bred from broodstock that consistently produce dogs with these unique physical characteristics, are being registered as The American Bully.
