On the windswept Shetland Islands north of Scotland, crofters needed a small, quick dog to keep sheep, ponies and poultry out of their gardens. The Shetland Sheepdog grew from those island herders, small Scottish collie-type dogs and some toy breed influence, and was later refined with Rough Collie crosses. It was first called the Shetland Collie, and the AKC registered its first Sheltie in 1911.
Today's Sheltie looks like a Collie in miniature, with a long, harsh coat over a dense undercoat, a mane and a refined, wedge-shaped head. Many are deeply loyal, sensitive and remarkably quick to learn, which helps explain their success in obedience and agility. They also tend to be vocal, reserved with strangers and heavy shedders, details worth weighing before adopting one.
