It is a breed of English origin and descends from the English Bulldog. But whereas its ancestor was used as a companion dog after the fights with bulls were banned, the American Bulldog was used for different jobs on farms. In this way, this turned out to be a little bigger than its English relative, to have longer legs and to be more nimble. After World War II, this breed almost disappeared, but an old campaigner - John D. Johnson from Summerville, Georgia succeeded to save and revitalize it. The best known subbreeds of this American Bulldog are from the type Johnson and Scott. The ones from the Johnson type have a larger size, with a big head and a short muzzle and have a higher tendency for aggression. Scott dogs are athletic, slender with longer legs.

The eyes are round, big, generally dark and have a wrinkle between them. The ears are medium-sized, half up (tulip shaped), cut or floppy.
