Do the dog breeds Patterdale Terrier and Shikoku both originate in Japan?
Shikoku (dog) The Shikoku (四国犬 , Shikoku-ken , alternative names: Kochi-ken, Mikawa Inu, Japanese Wolfdog) is a native, primitive Japanese breed of dog from Shikoku island that is similar to a Shiba Inu. The Shikoku was recently added as recognized breed of the American Kennel Club as an AKC FSS standard [ Foundation Stock Service ], it is recognized by the Japan Kennel Club, an organization recognized by AKC as an official foreign registry (AKC recognizes the Shiba Inu, however). The Shikoku is also in the Canadian Kennel Club Hound group and the United Kennel Club, awaiting full recognition. In 1937 the Japanese Crown recognized the Shikoku dog as a living "natural monument" of Japan.
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.
