, dogs stand from and bitches from . Healthy adults typically weigh between . The head is not overly large in comparison to the body; the muzzle is long, broad and slightly pointed, the lips are not pendulous and the ears are small and triangular and hang flat to the head. The neck is short and strong, the chest broad and moderately deep, and the tail long, hanging low when the dog is at rest but curling over the back when the dog is roused. Unusually, the dewclaws on the hind legs are double; absence of these is considered a disqualifying fault for showing.
The coat is long, thick and double, providing protection from harsh weather; the long flat outer coat is particularly long around the neck, the tail and the backs of the legs, the under coat is fine and thick. The dogs are predominantly white in colour, 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. Purebred examples of the breed with black patches are sometimes seen in litters; such colouration is considered a disqualifying fault for show dogs.

s; in this role they were usually fitted with a heavy iron wolf collar studded with long nails for protection when fighting off wolves. They were often used by shepherds in combination with the much smaller Pyrenean Sheepdog, the former guarding the flocks and the latter herding them. They were also used to smuggle contraband between France and Spain, carrying packs over the Pyrenees on routes impassable to humans to avoid detection by customs officials.

were experiencing problems with stray dogs attacking their flocks, so the French ITOVIC commenced an experiment with around 15 Pyrenean Mountain Dogs given to farmers. By the late 1980s the ITOVIC experiment had been completed and an association, APAP, had been formed with around 15 Pyrenean Mountain Dog breeders, with the objective of providing suitable livestock guardian dogs to potential farmers, and by 1991 around 100 dogs were working on farms.

had reported unusual stock predation, which was, at the time, attributed by authorities to uncontrolled domestic dogs. Wolves are protected in France; in order to protect the livelihoods of farmers from wolf predation, since the late 1990s, the French government has subsidized various methods of protecting flocks from depredation, including electrified pasture fencing, secured electrified night pens, hiring of additional farm hands, and the purchase, training and upkeep of livestock guardian dogs. After the extirpation of wolves from France in the 1800s, livestock guardian dogs had been absent from the French Alps for over a century; when wolves resettled the country in the 1990s, the French Pyrenean Mountain Dog was the breed selected for use, as the ITOVIC trials had already been conducted with the breed, and within the country, the APAP was breeding Pyrenean Mountain Dogs specifically for the purpose.

into the Pyrenees, in order to save the species from extirpation from the region by genetic inbreeding, as the local population had been reduced to an estimated six bears. With the increased numbers of bears in the region, local shepherds reported increases of stock losses to bear predation, particularly in the summer months, when shepherds move their flocks into the mountains to graze the summer alpine pastures. To assist the shepherds, government funding was provided to implement the same protection measures as those employed for wolves, and Pyrenean Mountain Dogs were given to farmers in the Pyrenees to guard flocks from predators. Studies conducted in the mid-2000s found shepherds who employed Pyrenean Mountain Dogs across the Pyrenees reported 90% fewer stock losses to predators than shepherds who did not employ the dogs. The re-employment of Pyrenean Mountain Dogs within the Pyrenees has not been without issues, with reports of hikers traversing the mountains being attacked by the livestock guardians protecting their flocks, leading to a bilingual pamphlet being produced to warn walkers and bikers against risky behaviours in order to decrease incidents.
In 2009 there were over 1000 Pyrenean Mountain Dogs being used to protect flocks against wolves in the Alps, and 500 protecting flocks in the Pyrenees. In 2019, French government funding was being provided for the upkeep of 4258 livestock guardian dogs throughout the country, 92% of which were in the French Alps and Provence, although it is estimated the total number of dogs being employed at the time was around 5000.

Health
A 2024 UK study found a life expectancy of 10.9 years for the breed compared to an average of 12.7 for purebreeds and 12 for crossbreeds. A 2005 Swedish study of insurance data found 58% of Pyrenees died by the age of 10, higher than the overall rate of 35% of dogs dying by the age of 10.
