In the early 20th century, pit bulls were used as catch dogs in America for semi-wild cattle and hogs, to hunt hogs, and drive livestock, and as family companions. But the dog fighting remained the main use of the breed until 1976 when it was outlawed in all states. Pit Bull Terriers successfully fill the role of companion dogs, working dogs, athletic sport dogs (Weight pulling, French Ring Sport, Top Dog), and police dogs, and therapy dog. Pit Bull Terriers also constitute the majority of dogs used for illegal dog fighting in America In addition, law enforcement organizations report these dogs are used for other nefarious purposes, such as guarding illegal narcotics operations, use against police, and as attack dogs.
