American Bully, breed of muscular companion dog (in contrast to a working dog) created in the United States in the 1980s and ’90s. With proper training and care, it can often be an excellent family dog. However, because of its strength and potential for aggression, this powerful breed has been banned or restricted in several countries, including the United Kingdom, Ireland, Turkey, and the United Arab Emirates.
The breed’s main foundation is the American Pit Bull Terrier, which was then crossed with various bulldog breeds, notably the English Bulldog, the American Bulldog, and the Olde English Bulldogge. The goal was to create a tougher-looking but milder breed, one featuring a wide chest, marked muscle development, and a powerful jaw but with a diminished instinct for aggression. Although Bullies may serve as loving and gentle pets, a degree of aggression is characteristic of the breed.
