The Pyrenean Mountain Dog, or Pyrenean Mountain Dog (said in French patou; in Gascon pastou or patou; written in Occitan: pastor) is an ancient breed of herding dog. It is used in the south-west of France and in the north-east of Spain, particularly in the Pyrenees for the protection of herds against predators, particularly the bears that live there. A large dog, strongly built, with long hair and white coat, it is mentioned in writings as early as the 14th century.

Getting to know the Great Pyrenees

Origins & history

A story told

In the Middle Ages, it is used to guard castles and protect flocks against predators (bears, wolves, lynx and even man). It is mentioned in the 14th century by Gaston Phoebus. Highly appreciated in the 17th century, it shared the glory of the court of King Louis XIV.

The first description of the patou appears in the book of the Count of Bylandt in 1897. The official standard with the Central Canine Society is registered in 1923, at the initiative of M. Sénac-Lagrange, member of the Meeting of admirers of Pyrenean dogs. The current standard has been very little modified since, only details have been added. The patou had become less common in the countryside due to the disappearance of large predators. Following the return of wolves to the Alps and the return of bears to the Pyrenees, it has experienced renewed interest among shepherds, forced to protect their flocks. In 1965, the breed was made famous by the French television series Belle and Sebastian, then by the Japanese animated version of the same name.

Character

Daily temperament

Integrated into the herd, it is a remarkable guardian. Its role is not to gather sheep but to protect them. To do this, it is accustomed from an early age to live with them, so it considers them as its family. If the dog detects an intruder, it barks and positions itself between the herd and what it considers a threat. Like all canines, the patou is capable of causing injury to humans, some cases having been reported in the press. The subject of difficult cohabitation of the patou at work with thousands of vacationers on vacation in the courses, alpine pastures and mountain pastures was the subject, in May 2015, of a written question to the Senate. In 2021, a breeder was thus convicted to a fine of €2,500, partially with suspension following several bites from its patous on hikers. "If these altercations increase, it is partly due to the increase in hikers. And with the return of the wolf to French forests in the 1990s, breeders have multiplied their means of protecting their herds". In the family, it is an animal that can be a good guardian, due to its selection as a protection dog. It possesses a good sense of family and knows how to recognize friends it has not seen for a long time. It is gentle with children and rather placid. It is unsuitable for city life and overcrowding. It is indeed a dog that needs space and whose powerful barking can turn out to be a source of nuisance for neighbors.

Health

Health watch

The Pyrenean Mountain Dog can present problems with the hips, and more rarely with the elbows, often of genetic origin. Like any large dog, it presents risks of shoulder osteochondritis dissecans (OCD), unilateral or bilateral, of patellar luxation, unilateral or bilateral or of entropion in the eyes. The female can have nine to twelve puppies. It lives about 12 years.

Around age 10, or even a bit earlier, the dog may have parrot's beaks that grow on the surface of the spine and can lead to complete paralysis of the limbs. Like any large dog, the patou is subject to torsion or dilation of the stomach; feeding it twice a day at adult age seems to be a solution to this fragility. Effort and stress before and after meals also seem to be practices to avoid. On a daily basis, the patou does not ingest large volumes of food; it therefore benefits from being particularly nutritious, energetic and digestible. Intemperate washing seems harmful to it. Dry brushing seems more suitable.
