A Staffordshire greyhound is a rare breed of dog indeed, but a very special breed. It is of course not a pure breed, but a hybrid or mix between the greyhound and the Staffordshire bull terrier. Where you will most likely find this particular mixed breed will be the United Kingdom. There is little information to suggest that greyhounds have been bred with Staffordshire bull terriers or American Staffordshire terriers in the United States.
