The Shetland Sheepdog, often known as the Sheltie, is a breed of herding dog that originated in the Shetland Islands of Scotland. The original name was Shetland Collie, but this caused controversy among the Rough Collie breeders of the time, so the breed's name was formally changed. This hard-working small dog is intelligent, vocal, excitable and willing to please. They are incredibly loyal to their owners to the point where they are often referred to as "shadows" due to their attachment to family. This breed was formally recognized by The Kennel Club (UK) in 1909.Like the Shetland pony, Shetland Cattle and the Shetland sheep, the Shetland Sheepdog is a hardy but diminutive breed developed to thrive amidst the harsh and meagre conditions of its native islands. While the Sheltie still excels at herding, today it is often raised as a farm dog and/or family pet.The Sheltie's origins are obscure, but it is not a direct descendant of the Rough Collie, which it largely resembles. Rather, the Sheltie is a descendant of small specimens of the Scottish Collie and the King Charles Spaniel. They were originally a small mixed-breed dog, often only about 8 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 the breed that would become the modern Shetland Sheepdog.
