The Great Pyrenees shed based on the climate. Sometimes they shed more than enough. So there are some possibilities of finding the white hairs on your clothes, furniture, or the floor. So grooming them frequently is your big task. The great Pyrenees have double coats; the topcoat is very long, and the undercoat is woolly. Mostly, they are white with tan, gray, badger, or reddish-brown markings.
