American Bulldogs descend from working bulldogs that settlers brought to the colonial South, where they caught loose cattle and hogs and guarded farms. After nearly vanishing following World War II, the type was rebuilt into two looks: the heavier, shorter-muzzled bully type and the leaner, more athletic standard type. Adults weigh about 60 to 115 pounds and are usually mostly white.
In Little Rock, that history shows up as a dog with stamina for river-trail miles and a protective streak that needs steady training. Early socialization and reward-based training matter, and a dog this strong needs a sturdy leash and secure fencing. Many shelter dogs labeled American Bulldog are mixes, so size and energy can vary a lot from one dog to the next.
