Bull Terrier
Despite the laws making dog fighting illegal, the activity continued for many years. Breeders determined a cross between the Old English Bulldog and Old English Terrier created a superior fighting dog with increased quickness and dexterity. This new breed of dog, called the bull and terrier, was a precursor to the Staffordshire Bull Terrier, Bull Terrier and American Pit Bull Terrier and accelerated the extinction of the Old English Bulldog.
