Pit bull is the common name for a type of dog. Formal breeds often considered in North America to be of the pit bull type include the American Pit Bull Terrier, American Staffordshire Terrier, and Staffordshire Bull Terrier. The American Bulldog is also sometimes included. Many of these breeds were originally developed as fighting dogs from cross breeding bull-baiting dogs (used to hold the faces and heads of larger animals such as bulls) and terriers. After the use of dogs in blood sports was banned, such dogs were used as catch dogs in the United States for semi-wild cattle and hogs, to hunt and drive livestock, and as family companions, although some owners still bred and used them for illegal dog fighting. This practice continues to this day, but is illegal in many nations.
