The Hound is a female dog-hound mix and has three puppies of her own for the Druids to train and attack people to keep them away from the castle at night during the Druids secret meetings. The Druids were driven out of Scotland because the people of Scotland thought they were strange & because of rumors of their religion of using black magic got around a lot. Scrooge said this about the hound, "It was a great glowing beast that viciously attacked anyone who got near the castle." And that's what it did for many years for the Druids.
