The Shetland Sheepdog, often known as the Sheltie, is a breed of herding dog. Less favored nicknames are the Toy Collie and the Minuature Collie. They are small dogs, and come in a variety of colors, such as sable, tri-color, and blue merle. They are very intelligent, vocal, excitable, energetic dogs who are always willing to please and work hard. They are partly derived from dogs used in the Shetland Isles for herding small sheep or, just as likely, for chasing sheep and birds out of the crofter's gardens, along with several very small or toy breeds such as the King Charles Spaniel (not to be confused with the more modern Cavalier King Charles Spaniel), the Pomeranian, and the now extinct Yakki Dog. The breed was formally recognized by The Kennel Club in 1909.〔(【引用サイトリンク】url=http://www.shetland-sheepdog.com/sheltie-history )〕 The Shetland Sheepdog's early history is not well known. Although of obscure origin, what is know is that the Sheltie is a direct descendant of the Colkie the Sheltie is a descendant of small specimens of the Scottish Collie and the King Charles Spaniel. It was developed to tend the diminutive sheep of the Shetland Islands, whose rugged, stormy shores have produced other small-statured animals such as the Shetland pony. Today it is raised as a farm dog and family pet.〔"Shetland sheepdog." The Columbia Encyclopedia. New York: Columbia University Press, 2008. Credo Reference. Web. 17 September 2012〕 They were originally a small mixed-breed dog, often only about 8 inches to 12 inches in height at the shoulder. in height and it is thought that the original Shetland herding dogs were of Spitz type, and were crossed with Collies from mainland Britain. In the early 20th century, James Loggie added a small Rough Collie to the breeding stock, and helped establish what would become the modern Shetland sheepdog. The original name of the breed was Shetland Collie, but this caused controversy among Rough Collie breeders at the time, so the breed's name was formally changed to Shetland Sheepdog.〔 ==History== Unlike many miniature breeds that resemble their larger counterparts, this breed was not developed simply by selectively breeding the Rough Collie for smaller and smaller size. The original sheepdog of Shetland was a Spitz-type dog, probably similar to the modern Icelandic Sheepdog. This dog was crossed with mainland working collies brought to the islands,〔(''The ancestral relationships of contemporary British herding breeds''.

The original Spitz-type working sheepdog of Shetland is now extinct, having been replaced for herding there by the Border Collie. The Shetland Sheepdog in its modern form has never been used as a working dog on Shetland, and ironically it is uncommon there. When the breed was originally introduced breeders called them Shetland Collies, which upset Rough Collie breeders, so the name was changed to Shetland Sheepdog.〔 During the early 20th century (up until the 1940s), additional crosses were made to Rough Collies to help retain the desired Rough Collie type – in fact, the first AKC Sheltie champion's dam was a purebred rough Collie. The year 1909, marked the initial recognition of the Sheltie by the English Kennel Club, with the first registered Sheltie being a female called Badenock Rose. The first Sheltie to be registered by the American Kennel Club was "Lord Scott" in 1911. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Shetland Sheepdog」の詳細全文を読む スポンサード リンク
