The Pyrenean Mountain Dog, known in the United States as the Great Pyrenees, is a large livestock guardian breed with ancient origins in the Pyrenees Mountains of southern France and northern Spain. Traditionally used to protect sheep and other livestock from predators, the breed has been a working companion to the Basque people for centuries. It also served as the official dog of the French royal court during the Middle Ages and was later used in World War II to haul artillery through mountain terrain.
Adult males typically weigh between 100 and 160 pounds, while females range from 85 to 115 pounds. The breed has a thick, weather-resistant double coat, most often white, though some dogs have patches of gray or tan on the ears, face, or body—a coloration known as blaireau. One of the breed’s distinguishing features is the presence of double dewclaws on the hind legs, which are a standard trait and should not be removed.
The Pyrenean Mountain Dog is independent, confident, and deeply loyal to its family and flock. Bred to make decisions without human direction, it retains a strong instinct to monitor its surroundings and protect those under its care. The breed is naturally reserved with strangers but can be gentle and affectionate with those it trusts.
