Greenlanddog
The Greenland Dog is a powerful, heavy-built dog. It has a broad, wedge-shaped head, slightly tilted eyes and small, triangular ears covered with thick fur that prevents frostbite. It has strong, muscular, short-haired legs. The tail is usually rolled along/across its back, but it may also hang down in a wolflike manner. When it lies down and curls up to rest, the tail often covers the nose. Its coat is of medium length and consists of two layers. The inner layer consists of short wool-like fur, the outer layer of longer, coarser, water-repellent fur. As a result of living in a pack structure very much similar to their wolf forebears, the Greenland dog takes a very firm and confident owner to make a good pet. Once one has won their respect, however, they can be very loyal and protective of their owners, especially if in a pack. The Greenland dog is one of the oldest breeds in the world.
