What were Bull Terriers bred for?
Bull Terriers were originally bred to participate in blood sports, including bull-baiting and dog fighting. The breed was created by crossing the Old English Bulldog with the now-extinct Old English Terrier. Later, other breeds, such as the Spanish Pointer, were introduced. When the cruel activities of bull-baiting and dog fighting were banned, the breed’s role shifted toward being a loving and friendly pet.
