American Bulldogs descend from working bulldogs that settlers brought to colonial America. On Southern farms they caught loose cattle and feral hogs and guarded the homestead. The type nearly vanished after World War II before John D. Johnson and Alan Scott revived it. Today there are two broad types, the heavier, shorter-muzzled Johnson or bully type and the leaner, more athletic Scott or standard type, and many dogs fall somewhere between.
Most are mostly white, weigh roughly 60 to 115 pounds and have a short coat that sheds moderately. Many are devoted, affectionate and confident, with a protective streak. In Santa Barbara, where leash rules apply on streets and trails, early socialization and steady reward-based training matter, because a strong dog needs reliable manners on a six-foot leash. Dogs vary, and a dog labeled American Bulldog may be a mix.
