Are both Bedlington Terrier and Border Collie bred for the same purposes?
Bedlington Terrier The Bedlington Terrier is a breed of small dog named after the mining town of Bedlington, Northumberland in North East England. Originally bred to hunt vermin in mines, the Bedlington Terrier has since been used in dog racing, numerous dog sports, as well as in conformation shows and as a companion dog. It is closely related to the Dandie Dinmont Terrier, Whippet and Otterhound.
American Staffordshire Terrier The American Staffordshire Terrier, also known as "Amstaff" (in the United States) or simply "Stafford", is a medium-sized, short-coated American dog breed. It is one of several breeds commonly known as pit bulls. In the early part of the twentieth century the breed gained social stature and was accepted by the American Kennel Club in 1936. The name was changed to reflect difference from the Staffordshire Bull Terrier of England.
