The Irish Staffordshire Bull Terrier has a
rowdy and multi-cultural past. Starting as a dog-fighting breed in Ireland and England, this breed is a mix between the bull dog and the terrier. The breed has continued to develop since its inception in the 19th century. As of 2010, the breed is registered in both the UK's Kennel Club and the American Kennel Club. While no longer a fighting dog, the breed is instead a household pet known for its fearlessness, its love of chewing things, and its ability to get along with older children in family homes.
Irish breeders developed a taller, leaner and more agile dog than the Kennel Club's Staffordshire dog. When Irish and English lawmakers officially banned the dog-fighting sport, few people were interested in buying or breeding the bull terrier. However, a refreshed interest in the dog revived in the 1980s when the dog was bought as a pet in the UK and in the U.S.
