American Bulldogs descend from working bulldogs that settlers brought to the South, where they caught loose cattle, held feral hogs and guarded farms. The breed nearly disappeared after World War II before dedicated fans rebuilt it. Today's dogs run about 60 to 115 pounds, usually mostly white, with a broad head and a muscular frame. Leaner dogs are often called Scott or standard type, and heavier, shorter-muzzled dogs Johnson or bully type.
Many are affectionate and eager to please, with a confident, protective streak and plenty of stamina. In Kennesaw's suburban neighborhoods that often means a dog who loves backyard time but needs real exercise and steady, reward-based training. Their strength makes early socialization and good leash manners important, and many shelter dogs labeled American Bulldog are mixes, so each dog's size and energy can differ.
