Sheltie is easier to say than "Shetland Sheepdog", which tells you where these dogs came from (Shetland Islands, near Scotland) and what they were bred to do (herd sheep). What they are not are "miniature Collies", even though they may look like it. It is likely that Collies and Shelties have the same ancestors. Shetland Sheepdogs are popular pets, thanks to their wonderful dispositions. They are smart and easy to train. About the only disadvantage is that they tend to be barky. The long coat should be brushed often, unless you don't mind the hair all over the carpet. As herding dogs they need plenty of daily exercise, and a leisurely walk around the block will not be enough. Shelties can be recognized by their long, thick coats with white "manes" and narrow snouts. They are small dogs, weighing between 10-20 lbs. Shetland Sheepdogs supposedly only come in two colors, black or sable. The sable or black can have several variations, including merle or tan. Shelties almsot always have a white collar.
