The Staffordshire Bull Terrier is a medium-sized, short-coated breed of dog. It is of English lineage and may be considered to be within the pit bull type.
The early bull and terrier types were not bred to resemble the breeds of today, but rather for the characteristic known as gameness, with the pitting of dogs against bear or bull; testing the strength and skill of the dogs. Landrace working dogs crossbred with bulldogs provided the ancestral foundation stock for the Staffordshire Bull Terrier. These bloodsports were officially eliminated in 1835 as Britain began to introduce animal welfare laws. A dog fighting another dog was cheaper to organise and easier to conceal from the law. Dog fighting involved gambling and a way to continue to test the animal; dogs were released into a pit, and the last dog still fighting or surviving was recognised the winner.
The modern breed is one that has a temperament ideally suitable for a companion dog. It is a dog worthy to show and was accepted by The Kennel Club of the United Kingdom as the Staffordshire Bull Terrier in 1935.
