The American Bully was developed in the United States in the 1980s and 1990s, mostly from the American Pit Bull Terrier with American Staffordshire Terrier and bulldog breeds added. The aim was a companion dog with a heavy, muscular frame and a people-loving nature. Bullies come in Pocket, Standard, Classic and XL sizes, and most have a short, close coat in nearly any color.
In Phoenix, the practical questions are heat and housing. Heavier and shorter-muzzled Bullies overheat faster, so plan walks around the temperature and keep a cool room available. Their strength makes early training and leash manners important, and gradual introductions help with other dogs. Many are affectionate, lean-on-you companions who love being near family, though each dog's history and training shape its behavior.
