The Staffordshire Terrier is a fairly old breed, originally from England. It originated from a cross between Bulldogs and Manchester Terriers and is the first of a group of breeds known today as the Staffordshire Terrier. Initially, the Staffordshire Terrier was used to bait bulls, bears, and other wild animals with dogs, but not when hunting, but in the ring. Accordingly, this breed has a rather bloody past.
They were also used in dog fights, since they needed a dog of relatively small size, but with a powerful grip and an undaunted character. At the same time, dogs were required to be friendly towards people, moreover, this had a purely professional necessity. When the clerk separated the dogs, he had to have at least some confidence that the dog in the heat of battle would not bite off his hand.
