American Bulldogs trace back to working bulldogs brought to the colonial South, where they caught loose cattle and feral hogs and guarded farms. The breed nearly disappeared after World War II before John D. Johnson and Alan Scott revived it, producing a heavier, shorter-muzzled bully type and a leaner, more athletic standard type. Most weigh 60 to 115 pounds and are mostly white, often with patches of red, brown or brindle.
Many are affectionate, confident and protective, with stamina to spare. That strength calls for early socialization, steady reward-based training and secure handling. The short coat sheds moderately year-round and needs little grooming, but Boca Raton's warmth makes exercise timing and a cool place to rest part of the routine. Many dogs labeled American Bulldog are mixes, so size and energy vary from dog to dog.
