A Shetland sheepdog is not a "mini-collie" but a distinct separate breed that actually has roots in the Border collie. A native of the Shetland Isles in far northern range of Scotland he was a dog developed to help on crofts, or small farms, where there wasn't much food to be had. A small dog was needed for that reason, yet a tireless worker in all kinds of weather which gave rise to selection for a durable coat and a loyalty to their owners.
