Before the nineteenth 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 tenderising 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. Early Bull and Terrier were not bred for the handsome visual specimen of today, rather they were bred for the characteristic known as gameness. The pitting of dogs against bear or bull tested the gameness, strength and skill of the dog. These early "proto-staffords" provided the ancestral foundation stock for the Staffordshire Bull Terrier, the American Pit Bull Terrier with the exception of the American Staffordshire Terrier.
These bloodsports were officially eliminated in 1835 as Britain began to introduce animal welfare laws. Since dogfights were cheaper to organise and far easier to conceal from the law than bull or bear baits, bloodsport proponents turned to pitting their dogs one against another instead. Dog fighting was used as both a bloodsport (often involving gambling) and as an effort to continue to test the quality of their stock. For decades afterwards, dog fighting clandestinely took place in pockets of working-class Britain and America. Dogs were released in a pit, and the last dog still fighting (or occasionally, the last dog surviving) was recognised as the winner. The quality of pluckiness or "gameness" was still highly prized, and dogs that gave up during a fight were reviled as "curs". As an important aside, fighting dogs were often handled in the pit during fights, by both their owners and the judge, so were bred to be as trustworthy with humans as they were aggressive towards other dogs.
It is this nefarious history that gives the Staffordshire his celebrated temperament, as in the words of the American Kennel Club: "from the past history of the Staffordshire Terrier, the modern dog draws its character of indomitable courage, high intelligence, and tenacity. This, coupled with its affection for its friends, and children in particular, its off-duty quietness and trustworthy stability, makes it a foremost all-purpose dog."
The breed attained UK Kennel Club recognition on 25 May 1925. Much of the groundwork to attain this status can be attributed to Joseph Dunn and Joe Mallan. Dunn and Mallan invited friends to a Staffordshire fanciers meeting at the Cross Guns Hotel, Cradley Heath, South Staffordshire (a hotel owned and managed by Mallan). About fifty breeders met at the hotel and formed the Original Staffordshire Terrier Club. The name was shortly changed to Staffordshire Terrier Club due to the Bull Terrier Club objecting the use of the word 'original'. Staffordshires were imported into the US during this time. Since that time the breed has grown to be one of the most popular breeds of dogs with a large representation at the Crufts Dog Show.
In the US many were imported by pit fighters and used in their breeding programs to produce the American Pit Bull Terrier and American Staffordshire Terrier. Many were imported by British nationals who brought their dogs with them or U.S. expatriates who fell in love with the breed in England and brought it home. Eventually through the campaign of many people the Staffordshire was recognised in the U.S. in 1976. He has a loyal following.
