The American Bulldog descends from working bulldogs that came to the American South with settlers and earned their keep catching cattle and hogs and guarding farms. The breed nearly disappeared after World War II before enthusiasts revived it, leaving two broad types: the leaner, more athletic Scott or standard type and the heavier, shorter-muzzled Johnson or bully type. Many dogs today are a blend, and plenty of shelter dogs labeled American Bulldogs are mixes.
Expect a muscular, mostly white dog with a short coat that sheds moderately all year. Many are affectionate and goofy with their families, confident with strangers and surprisingly strong on a leash. In Oceanside that means a sturdy harness or collar for trail walks, early socialization, and reward-based training that starts the first week at home.
