The American Bully was developed in the United States in the 1980s and 1990s, mainly from the American Pit Bull Terrier, with American Staffordshire Terrier and bulldog breeds mixed in. The goal was a companion with a heavy, muscular frame and a people-loving temperament. Bullies come in several size varieties, from compact Pockets to tall XLs, in nearly every color.
Many are affectionate and deeply attached to their families, though tolerance of other dogs varies, so gradual introductions help. In a city where most walks mean sidewalks, shared parks and other leashed dogs, early training and leash manners matter. Heavier, shorter-muzzled Bullies overheat more easily, and keeping a muscular build lean protects the joints. Size, energy and personality vary widely from dog to dog.
