Staffordshire Bull Terriers. American Bully. The American Bully was recognized as a breed by the United Kennel Club (UKC) in the summer of 2013. It first appeared in the 1990s and was created by crossing American Pit Bull Terriers, American Staffordshire Terriers, and other breeds.
Pit Bulls descend from crosses between Bulldogs and Terriers. The goal was to create a dog with the strength and tenacity of the Bulldog and the speed and agility of the Terrier. American Pit Bull Terriers were once an iconic American breed. They were American military mascots, advertising stars, and popular farm and family dogs. But when dog fighters criminally exploited the breedâs loyalty, tenacity and bold nature, the Pittieâs reputation took a hit from which it hasnât yet recovered.
