There were several varieties of this combination betweenbulldogand terrier, depending on the location (town or country) and the dogs chosen for the crossing. In Ireland, they used the old Irish bulldog with different terriers and some insertion of hunting sighthound/terrier crosses. In England, there were several varieties such as theWalsalltype and the Cradley Heath type. Phil Drabble reported that among the various types of bull and terrier, the type from Cradley Heath was recognised as a separate breed to be named theStaffordshire Bull Terrier. In the 19th century, the Walsall type was carried by immigrants to the United States, where it served as an important component for the genetic basis of the American Pit Bull Terrier breed, through specimens such as the dog Lloyd’s Pilot and the Colby bloodline, strongly combined with Irish strains. The anatomy of the bull and terrier is the result of selective breeding for the purpose of hunting, dog fighting and baiting.
