Hailing from the Shetland Islands just off of Scotland, the Shetland Sheepdog was developed as a miniature Collie. Originally the Collies of Scotland were medium-sized dogs, and presumably the smaller versions of these were bred to create the Sheltie.
Shetland Sheepdog and Rough Collie - YES, separate breeds. one is a miniature being the Shetland Sheepdog like a MINI ME of the Original Rough Collie! Great for people who would love a full sized Collie but not the Room!
