About Great Pyrenees

from Wikipedia…

The Pyrenean Mountain Dog is a very large and heavily built breed of livestock guardian dog that, according to the Société Centrale Canine's breed standard, males stand from 70 to 82 centimeters (28 to 32 in) and females from 65 to 77 centimeters (26 to 30 in). Healthy adults typically weigh between 55 and 75 kilograms (121 and 165 lb). The breed's head is not overly large in comparison to the body; it has a long, broad and slightly pointed muzzle with lips that are not pendulous and small triangular ears that hang flat to the head. The breed has a short and strong neck, a broad and moderately deep chest and a long tail that hangs low when the dog is at rest but curls over the dog's back when the dog is roused. A distinctive feature of the breed is that it possesses double dewclaws on the hind legs, the absence of which is considered a disqualifying fault in conformation shows.

The breed has a long and thick double coat that provides it protection from harsh weather; the long and flat outer coat is particularly long around the neck, tail and backs of the legs, and it has a fine and thick under coat. The breed is predominantly white in color, with patches of black, badger, grey or various shades of tan found mostly on the head; badger is defined as a mixture of brown, black, grey and white hairs and is commonly seen in puppies but usually fades as the dog ages. Whilst purebred examples of the breed with black patches are seen in litters, such coloration is considered a fault by show dog fanciers and is not permitted in conformation shows.
