American Bulldogs descend from working bulldogs that colonial settlers brought to America. In the South they became farm dogs that caught cattle and feral hogs and guarded homesteads. The breed nearly vanished after World War II until John D. Johnson and later Alan Scott revived it, producing a heavier, shorter-muzzled Johnson or bully type and a leaner Scott or standard type. Many dogs are a mix of both. Adults weigh roughly 60 to 115 pounds and are mostly white, often with patches.
Many American Bulldogs are devoted, affectionate family dogs with a protective streak and plenty of stamina, so early socialization and reward-based training matter. In Monroe, a dog this size does best with a securely fenced yard or a dependable routine of long walks. Dogs vary, and plenty labeled American Bulldogs are mixes, so look at each dog's size and energy, not just the label.
