The American Bully is a recently developed breed of dog which was bred to be a companion dog and show version of the American Pit Bull Terrier and the American Staffordshire Terrier. First appearing in the 1990’s, the American Bully is rapidly increasing in popularity, more so than almost any other rare bred both in the United States and abroad. The American Bully is best known for its tough and intimidating appearance and its friendly but protective nature. American Bullies are not currently recognized by any major canine organization but a few smaller registries have recognized them and there are several breed specific clubs dedicated specifically to them. The American Bully is usually considered to be a type of Pit Bull, referring to the general type collectively known as Bully Breeds, not the specific breed.
