The Shetland Sheepdog, also known as the Sheltie, is a breed of herding dog. The original name of this breed was Shetland Collie, but this caused controversy among the Rough Collie breeders at the time, so the breed's name was formally changed to Shetland Sheepdog. This small dog is intelligent, vocal, excitable, energetic and willing to please and work hard. The breed was formally recognized by The Kennel Club in 1909.
The Shetland Sheepdog's early history is not well known. Although of obscure origin, what is known is that the Sheltie is a direct descendant of the Collie. 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. They were originally a small mixed-breed dog, often only about 8 inches to 12 inches in height at the shoulder, and it is thought that the original Shetland herding dogs were of the 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.
