General Appearance: The Great Pyrenees dog conveys the distinct impression of elegance and unsurpassed beauty combined with great overall size and majesty. He has a white or principally white coat that may contain markings of badger, gray, or varying shades of tan. He possesses a keen intelligence and a kindly, while regal, expression. Exhibiting a unique elegance of bearing and movement, his soundness and coordination show unmistakably the purpose for which he has been bred, the strenuous work of guarding the flocks in all kinds of weather on the steep mountain slopes of the Pyrenees.
