The Manchester Terrier is a direct descendant of the early English Black and Tan Terrier, which was highly prized for its working ability as a "ratting" dog in the industrial areas of the North of England.
These early dogs were more rugged than the breed is today, but the Manchester still maintains the physical structure of a working terrier. When first officially classified, all smooth-coated, black and tan terriers (including the smaller, Toy, variety) were called Old English Terriers.
The present breed type was said to be influenced by the possible introduction of Whippet blood for refinement, plus theBull Terrierand White English Terrier. Samuel Handley of Manchester, England, is credited with stabilizing the breed. As a result of his efforts, the breed became known as the Manchester.
