Staffordshire Bull Terriers

History
Before the 19th century, bloodsports such as bull baiting, bear baiting and cock fighting were common. Bulls brought to market were set upon by dogs as a way of tenderizing the meat and providing entertainment for the spectators; and dog fights with bears, bulls and other animals were often organised as entertainment for both royalty and commoners.
