The average coat length is between 6 and 9 cm. Their fur tends to grow longer across the shoulders, under the belly, and around the throat.

They resemble the Saint Bernard in terms of size and shape.

They are also very loyal, and if they feel that their family is being threatened they will use their strength and become very hostile towards enemies.

They are gentle with their pack and will act protective of children in their homes.

They will not hesitate to defend their family members if they think a threat is nearby. Overall they are loving and kind dogs that require plenty of socialization from a very young age.

Health Problems of the Mastiff

The Pyrenean Mastiff is prone to health conditions that are typical of large size breeds.

These types of health conditions would include hip dysplasia and bloat. 

Make sure to keep bloat at bay that you are feeding your dog multiple smaller meals a day. They need to eat a lot of food but not all at once, or they can get severely sick.

Hip dysplasia is another condition that most larger dog breeds get. The way to prevent this is to have the hip score done on your dog as a puppy or by checking out the parents of the puppy.

If you ever have any concerns with your dog’s overall health, make sure you are checking it over with a health professional.

Pyrenean Mastiff


I hope by now you have learned that the Pyrenean Mastiff was originally bred as wild outside mountain dogs. 

That being said that means this breed is used to being outdoors getting a lot of exercise. 

These dogs are the happiest when they can go outside as they please to roam, play, eat, and sleep.

If your dog cant freely go outside where you live then you need to take your dog on multiple walks giving them over a total of an hour of exercise a day. 

If your dog has a day where they get more exercise than usual then they may be hungrier or need more food than usual. 


Pyrenean MastiffThe Mastiff breeds are very big dogs, so as you can imagine, they eat a lot of food.

This breed needs three cups of food a day. Now don’t give your dog three cups of food all at once. They need to have it divided into smaller meals throughout the day.

This will prevent bloat, which is crucially important in bigger dogs.  Separate the meals into breakfast, lunch, and dinner for your dog.

The average cost per day for high-quality large dog food is around $1.50 to $2.oo a day.

If your dog has been outside more playing and running around, they may need four cups of food instead of three. You will need to gauge this on your dog’s activity level.

Grooming the Mastiff

Pyrenean Mastiffs have a heavy coat that requires regular combing and brushing.

This dog is a regular shedder, so the more frequently it is brushed, the less fur owners will find on furniture and carpets.

The dog’s face, primarily around the ears and eyes, should be kept dry.

Origin of the Pyrenean Mastiff

The Pyrenean Mastiff we know today descended from ancient livestock dogs. These canines were responsible for guarding the animals left in their care.

Since 1977, a modern purebred was documented by the Spain-based Club del Mastin del Pirineo de Espana.

They are currently being promoted in other countries including the United States by the Pyrenean Mastiff Club of America. The Federation Cynologique Internationale (CFI) recognized the breed in 1982.


No notable sub-groups currently exist.

Pyrenean Mastiff Puppies

If you are not ready to raise such a big dog, then I suggest finding a different breed to adopt.

It is important to begin early socialization with your dog. This will make them feel more comfortable around people and children.

It is also always a good idea to start training your puppy early. They will learn obedience and right from wrong.
