American Bulldogs descend from working bulldogs that colonial settlers brought to America, where they became farm dogs in the South, catching loose cattle and feral hogs and guarding homesteads. The type nearly vanished after World War II until John D. Johnson and later Alan Scott revived it. The result is two looks: the heavier, shorter-muzzled Johnson or bully type and the leaner, more athletic Scott or standard type, with many dogs falling somewhere between.
Adults usually weigh 60 to 115 pounds and are mostly white, with a short coat that sheds moderately. Many are devoted, affectionate and confident, with a protective streak and plenty of stamina. In Columbus, that strength means a sturdy harness and consistent reward-based training matter from the first week. Many shelter dogs labeled American Bulldogs are mixes, so size and energy can vary a lot from one dog to the next.
