Contrary to popular belief, Shelties are not miniature Collies, but are their own unique breed. A fairly small breed (usually under 25lbs in adulthood), Shetland Sheepdogs are wonderful family pets. They are great with children and other animals, adore their people, and are very willing to obey and please their owners. They are extremely intelligent and quick to learn, and also tend to be fairly vocal. These gentle, playful pups are well-suited for active families.
