A composed, unhurried dog that is hard to rattle. It bonds closely with the people and animals it considers its own and tends to hold back and watch strangers before deciding what to make of them. Centuries of guarding flocks without a shepherd close by have made it self-reliant, so it listens best to patient, fair and consistent handling rather than pressure.1257

Coat and looks how to spot one
long, dense double coat
A big, powerful dog that still moves with some elegance, slightly longer than tall. The outer coat is long, flat and supple over a thick woolly undercoat, a little crisper over the shoulders and back and fuller around the neck and on the plumed tail. A signature detail is the pair of well-formed double dewclaws on each hind leg.154
Colourswhitewhite with badger (grey) markingswhite with wolf-grey markingswhite with pale yellow markingswhite with orange markings15
Daily activity how busy a day looks
Moderate. Around an hour a day for an adult is plenty, such as steady walks or hikes; it is not a dog that needs constant high-energy play. Puppies should have limited exercise while they are still growing.832
Grooming and care the hands-on bits
Brush two to three times a week with a slicker brush, and daily during the heavy spring and autumn moults, to keep the undercoat from matting. Expect white hair year-round. Keep the double hind dewclaws trimmed along with the other nails. Positive, reward-based training with plenty of patience suits this independent breed.238
Home where they are happiest
Needs a large home and a large, securely fenced garden; apartment life is a poor fit. The heavy coat makes it most comfortable in cool climates, so shade and care are needed in hot or humid weather. Can live in town or country.82
Food basics what goes in the bowl
A complete, balanced diet made for giant breeds. Puppies benefit from a large-breed growth food that keeps growth steady and controlled; adults should be kept lean with portions matched to their activity level.2
Company who they like around
Very attached to its household and happiest living as part of the family, where it can quietly keep an eye on everyone. Early socialisation helps it stay relaxed with visitors. Many live peacefully with other household pets.257
The story where it all began
Large white flock guardians have worked in the Pyrenees for as long as records reach. Their ancestors are thought to have been guardian dogs that came west from Asia Minor, and the breed then developed in relative isolation in the mountains, protecting sheep from wolves and bears and also standing guard at castles. In the 1670s the young Dauphin brought one back from Barèges, and the breed became fashionable at the court of Louis XIV. Once wolves disappeared from the range in the 1800s, numbers fell sharply and the breed came close to vanishing. Bernard Senac-Lagrange tracked down good specimens, founded the Réunion des Amateurs de Chiens Pyrénéens in 1923 and wrote the first standard, which has changed little since. In 1931 Mary Crane imported dogs to the United States, her male Urdos became a foundation sire, and the AKC recognised the breed in 1934. The FCI gave definitive recognition in 1955. Today the breed is back at work guarding flocks in the Alps and Pyrenees as well as living as a family companion.1496
Fun facts for the dinner table

Working dogs traditionally wore a heavy iron collar studded with long spikes to protect their throats when facing wolves.4

In 1824 the Marquis de Lafayette sent two male Pyreneans to the United States as a gift to John Stuart Skinner.9
3
Its hind legs carry double dewclaws, a feature the breed standard specifically asks for.1
4
In the past the dogs were used to carry packs of goods over Pyrenean mountain routes too rough for people.4
5
It is one of the breeds used in the 1830s to create the Leonberger.4
6
A 1986 survey found that 57% of livestock guardian dogs working on US farms were Great Pyrenees.4

Shepherds using these dogs in the mid-2000s reported about 90% fewer flock losses to predators.4

The French nickname 'Patou' comes from 'pâtre', an old word for shepherd.4
Where the name comes from the story behind it
The breed is named after the Pyrenees Mountains, the mountain range between France and Spain, where it originated. In France, it is commonly called the Patou, and in the US it is known as the Great Pyrenees.10
This morning, I checked my flock (my humans) were all still in their beds. Then I did a patrol of the yard, making sure no sneaky squirrels got too close. My human laughed and said I'm a good guardian. After breakfast, I found the perfect spot on the cool floor and dozed while the kids played. When the mailman came, I gave a big, deep bark to let him know I'm on duty. My human gave me a scratch behind the ears and said I'm a good boy. Later, we went for a walk, and I made sure to keep everyone together. Now I'm lying on the grass, watching the stars, ready to guard my family all night.

Treats they will love homemade and simple
Pyrenean Mountain Dog tip
Choose low-fat, single-protein treats to support a sensitive stomach and avoid adding extra weight. Because this deep-chested breed is prone to bloat, give treats in calm, separate sessions rather than around mealtimes.
Not veterinary advice. Check with your vet first if your pet has allergies, a health condition, is on a special diet or is pregnant. Treats should stay a small part of the daily food. Cut to a safe size and supervise. Terms of use
Owner questions the things everyone asks
How often should I feed my Pyrenean Mountain Dog, and at what times?
Feed adult Pyrenean Mountain Dogs at least two meals a day, and puppies three to four smaller meals. Stick to consistent times and avoid free feeding for puppies. Keep portions matched to activity to maintain a lean, healthy weight.132
What should a Pyrenean Mountain Dog eat, and which foods are dangerous?
Feed a complete balanced diet made for giant breeds. Avoid dangerous foods like chocolate, grapes, raisins, onion, garlic, and xylitol. Always check with your vet for the best diet plan.214
How often should I bathe a Pyrenean Mountain Dog?
A bath every 70 days (about every two to three months) is a good starting plan. You can bathe more often if your dog gets dirty, using a gentle dog shampoo.15Pet Wiki plan
How often does a Pyrenean Mountain Dog need brushing?
Brush two to three times a week with a slicker brush, and daily during heavy spring and autumn shedding. This keeps the thick undercoat from matting and controls the year-round white hair.238Pet Wiki plan
How do I trim a Pyrenean Mountain Dog's nails, and how often?
Trim nails every four weeks or sooner if you hear clicking on the floor. Cut a little at a time, stopping before the quick, and don't forget the double hind dewclaws.23815Pet Wiki plan
How much exercise does a Pyrenean Mountain Dog need?
An adult Pyrenean Mountain Dog needs about 45 minutes to an hour of steady exercise daily, like walks or hikes. Puppies need limited exercise while growing. This breed enjoys calm, moderate activity.832Pet Wiki plan
How do I look after a Pyrenean Mountain Dog's teeth and ears?
Brush teeth daily if possible, at least two to three times a week, using dog toothpaste. Check ears weekly and dry them gently; never insert anything into the ear canal.15Pet Wiki plan
How long does a Pyrenean Mountain Dog live?
Pyrenean Mountain Dogs typically live 10 to 12 years. With good care and regular vet checkups, they can enjoy a long, healthy life.2
Is a Pyrenean Mountain Dog good with children and other pets?
Yes, they are wonderful with children and other pets they are raised with, as they bond closely with their family. Early socialisation helps them stay relaxed with visitors. They are gentle and protective.257
Can a Pyrenean Mountain Dog be left alone?
This breed is self-reliant but very attached to its family, so it may not do well if left alone for long periods. It's best to ask a good breeder or your vet for advice specific to your dog.
