The American Bully is a relatively new breed of dog that was developed in the 1990s. It is a companion breed that was created by crossing several bulldog and terrier breeds, including the American Pit Bull Terrier, American Staffordshire Terrier, and others.
Pocket American Bullies are the smallest of the breed, typically standing between 13 to 17 inches at the shoulder.
Standard American Bullies are medium-sized dogs, with males typically standing between 17 to 20 inches at the shoulder, and females slightly smaller.
Classic American Bullies are similar in size to the Standard type but have a more traditional bulldog appearance.
XL American Bullies are the largest type, with males standing over 20 inches tall at the shoulder.
