American Bulldogs have become increasingly popular in the United States, though they are distinct from the English Bulldog registered with the American Kennel Club. Originally developed by immigrant farmers in the American South to serve as working farm dogs capable of catching and holding wild boar and feral pigs, as well as guarding farms and herding livestock, the American Bulldog is a larger, more athletic, and generally healthier dog than its English counterpart. They were nearly extinct by the end of World War II before dedicated breeders revived the population.
American Bulldogs are large, muscular dogs typically weighing between 60 and 120 pounds, with a powerful, athletic build and a confident, determined temperament. They come in several distinct types, most notably the Johnson or Classic type (heavier, with a shorter muzzle and more pronounced brachycephalic features) and the Scott or Performance type (more athletic, with a longer muzzle and less extreme conformation). The breed is not currently fully recognized by the AKC, though it is recognized by the United Kennel Club (UKC).
American Bulldogs require an experienced owner capable of providing consistent, firm training and confident leadership. They are loyal, protective, and deeply bonded to their families but require thorough socialization from puppyhood to manage their natural wariness toward strangers and potential same-sex dog aggression. Their athleticism and working heritage demands significant daily exercise. Common health concerns include hip dysplasia, elbow dysplasia, cherry eye, neuronal ceroid lipofuscinosis (a genetic neurological disease in some lines), and skin fold infections in the heavier-typed individuals. With appropriate selection, training, and socialization, American Bulldogs are devoted and impressive working companions.
