"Pit Bull" came from dogs that had Bulldog bloodline, that were fought in Pits. Before Dog Fighting, they were used for Bull & Bear Baiting & Ratting. The Bull & Terrier Breeds divided into American Pit Bull Terrier, American Staffordshire Terrier & Staffordshire Bull Terrier. Before being called APBT- they were called the pit dog, the 1/2 & 1/2, Yankee dog, and more. The Bull & Terrier Breeds came about by mixing the White Terrier w/ Bulldogs, they chose the Terrier for it's High Prey Drive/ Agility & Determination & the Bulldog for the Strength & Endurance to create what we know as the " Pit Bull" Breeds. When Imported to the USA, people in the East Coast still used the dogs for fighting, while Farmers moved West & used them as Farm/ Livestock dogs.
