The American Bulldog grew out of working bulldogs brought to the colonial South, where they caught loose cattle and feral hogs and guarded farms. The type nearly disappeared after World War II until John D. Johnson and later Alan Scott revived it, leaving two looks: the heavier, shorter-muzzled Johnson type and the leaner, more athletic Scott type. Adults weigh roughly 60 to 115 pounds and are mostly white.
Many are affectionate with their families and wary of strangers, with plenty of stamina. In Abilene, a dog this strong needs secure fencing and a sturdy leash, plus early socialization and steady reward-based training. Many dogs labeled American Bulldogs are mixes, so size and energy vary from dog to dog.
