About the Pyrenean Mastiff
The Pyrenean Mastiff is a very large, strong and muscular dog with solid bone, a deep chest, a large head and a broad, deep muzzle. Despite its size it is remarkably light on its feet and should never look slow or sluggish. It is typically calm and friendly, and wonderfully loyal to its owner and family.

Once known as the Navarra Mastiff, the breed developed in the Pyrenean region between Aragon and Navarra. It belongs to the Molosser family and has always been used as a flock guardian, protecting herds from predators such as the wolf and the bear. To protect its neck and throat while working, it often wore a heavy spiked collar.
The breed has adapted well to modern life as a guardian of the home and of country estates. In the UK it is on the Royal Kennel Club's Imported Breed Register.
Pyrenean Mastiff temperament
The ideal Pyrenean Mastiff is friendly towards people, calm, noble and intelligent. It is courageous and confident with strangers and never backs away, and it is good-natured towards other animals and aware of its own great size.
It is a guardian at heart: calm by nature, it can be aggressive when doing the job it was bred for, and it will guard and protect when it judges it necessary.
Size and appearance
This is a very large breed with no upper size limit. The breed standard sets minimum heights of 77 cm at the shoulder for males and 72 cm for females, and ideal heights are around 81 cm for males and 73.5 cm for females. The neck is protected by loose skin and a distinct double dewlap.
The coat is dense, thick, coarse and of moderate length, ideally 6–9 cm along the back, and longer on the shoulders, neck, underside, backs of the legs and tail. The base colour is always white, with a well-defined mask and patches in colours such as grey, golden yellow, brown, black, silver, beige or sand. Breed standard colours for registration are grey and white, and white, grey and sand.
How much exercise does a Pyrenean Mastiff need?
Up to an hour of exercise a day is usually enough for this breed. The Royal Kennel Club suggests a large house with a large garden.
Training a Pyrenean Mastiff
The breed standard describes the Pyrenean Mastiff as easily trained, which is one reason it makes an excellent guard for country estates and their owners today. Bear in mind that guarding is what it was bred for, and it will guard and protect when it thinks it is necessary.
Pyrenean Mastiff grooming
The thick coat needs grooming every day, and the Pyrenean Mastiff does shed.
Pyrenean Mastiff health
Not yet reviewed by a vet. This is general information, not veterinary advice: speak to your vet about your own dog’s health.
The Royal Kennel Club does not currently list breed-specific health screening tests for the Pyrenean Mastiff, and the breed is in Breed Watch Category 1, meaning no specific points of concern have been identified for judges. The Royal Kennel Club gives the lifespan as under 10 years. If you are thinking of buying a puppy, ask the breeder about the health of the parents and use the Royal Kennel Club's Health Test Results Finder for any tests they have had.

What health checks should you ask about?
Responsible breeders and rescues are happy to talk about health, and any pressure to decide quickly is a reason to walk away. Before taking a Pyrenean Mastiff home, it is reasonable to ask about:
- Health testing of the parents. Ask which health tests the parents have had for conditions known in the breed, and to see the results.
- Veterinary and vaccination records. Puppies should have had a first vaccination and a vet check, with records you can take home.
- Microchip information. In England, Scotland and Wales puppies must be microchipped and registered by eight weeks old. Ask who the chip is registered to and how the transfer works.
- Registration paperwork. Registration papers, where they apply, record pedigree. They do not by themselves prove health or how a puppy was raised.
How much does a Pyrenean Mastiff cost to own?
There are two costs: bringing a Pyrenean Mastiff home, and looking after one well. Puppy prices depend on the breeder, health testing and demand; the adverts below show what sellers are asking today.
Ongoing costs are the ones new owners most often underestimate: food, insurance (which usually rises with age), routine vet care, vaccinations and parasite treatment, dental care, grooming, training, bedding and equipment, and boarding or a sitter for holidays. Budget for the whole of the dog’s life, typically up to 10 years, not just the first year.
Buying a Pyrenean Mastiff
If you have decided the Pyrenean Mastiff suits your life, take the same care choosing where your dog comes from. Meet the puppy in person, see it with its mother, and look at how the litter is raised.
- Check who you are dealing with: every Mypetzilla advert shows the seller type and what we have checked.
- Ask about health testing, vaccinations and the microchip before you commit.
- Take your time. Do not be rushed by deposits or "last one left" stories.
- Meet in person before paying anything, and keep conversations on Mypetzilla.
Adopting a Pyrenean Mastiff
Pyrenean Mastiffs do come up for adoption, through rescue organisations, breed rescues and private rehoming, often because an owner’s circumstances have changed rather than any fault of the dog. An adult dog arrives as a known quantity: its size, coat and character are already on show.
Rescues will usually talk you through the dog’s history, any medical care, and the home it needs, including children, other animals and time alone. Be honest about your circumstances: a good rescue would rather place a dog once, well.
