Pyrenean Mastiff History

The Pyrenean Mastiff we know today is 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. In addition, the Federation Cynologique Internationale (CFI) recognized the breed in 1982.

The Pyrenean Mastiff is not currently accepted into the American kennel club but it is part of their foundation stock service. This helps the purebred breed still develop where they can maintain their records. People can still go to AKC to find breeders and information about this breed.

Another fun fact about the Pyrenean Mastiff is that they used to wear collars with large spikes on the ends to protect them when they were outdoors from wolves.


The Pyrenean Mastiff is a very large dog breed. You will also notice that this breed is quite muscular. It has a very fluffy coat that is very noticeable for this dog breed. 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.

The Pyrenean Mastiff has ears that fold and sit on the side of the head and eyes that have that droopy effect. The muzzle isn’t too long on this breed.

Pyrenean Mastiff Coat

Pyrenean Mastiffs are known for their very thick coat. The coat is medium to long in length, and this breed does have an undercoat. This coat actually protects the breed from the outside weather elements.

Since this breed has such a thick, dense coat, it means it will shed quite a lot. I suggest grooming your Pyrenean on a regular basis to help combat the hair situation and remove loose hairs that would end up all over your home. Below you will see some of the coat colors that your dog may possibly come in.

What Colors Do They Come In?

They have a thick coat that is white with large dark spots that can range from black to tan. Here are all the color options that you might see in a Pyrenean Mastiff:

  • Black
  • Brown
  • Gray
  • Sandy
  • Beige
  • Golden
  • Light Brown
  • White

This breed will have the traditional black nose and brown eyes.

Pyrenean Mastiff Temperament

Pyrenean Mastiff puppies grow up to be self-reliant dogs that are generally docile and even-tempered. 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. However, the Pyrenean Mastiff will still display an ingrained suspicion of strangers they meet, even with good socializing.

This breed isn’t one of those separation anxiety breeds. You can certainly leave this breed home alone for periods of time, say if you need to go to work, etc. However, you still do not want to leave your dog home by itself for too long.

This breed can still be a wonderful member of the family, and they do make great family companions. Do your research and make sure you know what you are getting into when choosing this dog breed.

Height & Weight

Pyrenean Mastiff breeders will warn most potential owners that this breed gets very large. The average male will stand 30 inches (77 cm), with females coming to 28 inches (71 cm) at the withers.

They usually weigh around 178 pounds (81 kg), but males can get as high as 220 pounds (100 kg).

Some potential owners do not realize how big the Pyrenean Mastiff can actually get. This breed will need a lot of space to grow and lay around, a yard to play in, and this breed will need a lot of food to replenish the lost calories it burns a day. Unfortunately, some dog owners cannot commit to some of these expenses.

Health Problems of the Mastiff

The Pyrenean Mastiff is prone to health conditions typical of large-sized breeds. These types of health conditions would include hip dysplasia and bloat.

Hip Dysplasia – 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.

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.

Intervertebral Disc Disease – This usually happens when your dog has a bulging or ruptured disk. This affects the dog’s spinal cord, which is painful and causes mobility issues. Again, your vet can help you with this issue.

Inflammatory Bowel Disease – This is a chronic syndrome that affects the gastrointestinal tract. This can give your dog reactions such as vomiting, diarrhea, and even stomach pain.

If you ever have any concerns with your dog’s overall health, make sure you are checking it over with a health professional. They can help manage your dog’s condition, and you should be taking your dog to yearly checkups as well.

Life Expectancy of the Pyrenean

The typical Pyrenean Mastiff will live approximately 10 to 13 years. As you know, some dogs can live longer than this and some shorter. It is important that you take your dog to yearly checkups with the veterinarian to ensure your dog stays healthy.

Living Conditions

Anyone interested in finding a Pyrenean Mastiff for sale should note that this dog will be enormous. Therefore, small living spaces are not recommended. It is not a high-energy canine, but it still needs space to live comfortably.

The Pyrenean Mastiff does really well in a fenced-in yard with plenty of room to run around and play. Unfortunately, small spaces do not work well for very large dog breeds. If you don’t have the room to accommodate this breed, then you may look into other breeds.

This breed is a gentle giant that is very protective of its family. They have a great temperament; they are very gentle with children, loveable, loyal, and reliable dogs. This breed is also very good with other dogs and other pets.

Pyrenean Mastiff Exercise

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 and 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 can’t 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. 

Keep in mind you do not need to fill this exercise requirement all at once. If that works best for you, you can split that hour up into multiple smaller sessions. 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 Mastiff Diet

Pyrenean Mastiff

The Mastiff breeds are very big dogs, so they eat a lot of food, as you can imagine. 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 $2.00 a day.

If your dog has been outside more playing and running around, they may need four cups of food instead of three. Again, 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 fewer fur owners will find on furniture and carpets. The dog’s face should be kept dry, primarily around the ears and eyes.

The coat of this breed can also get tangled and matted easily, and that is why it is so important to keep your dog regularly groomed. Also, when brushing your dog’s teeth, look for a dog-friendly toothpaste that helps prevent dental diseases that this breed could be prone to.

As always, it is important to overall check your dog for sores, rashes, or cuts. Make sure you bathe your dog about once a month or when it is physically dirty. Trim your dog’s nails but not too short that way, you don’t cut into a nerve.

Pyrenean Mastiff Training

Training is an important aspect of any dog. You will want to do some training with your Pyrenean Mastiff when it is a puppy. You can start with potty training and work yourself up from there to obedience training.

Training will take effort, but the time put into it will pay off. You will also want to start socializing your dog with different people, children, pets, and even noises. This creates a well-rounded and calm dog. You should praise your dog during training to let it know that it is doing a good job.

Pyrenean Mastiff Puppies

Now you want to keep in mind that while your Pyrenean Mastiff puppy is still small, they will grow up to be very large big dogs. 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.

When looking for a Pyrenean Mastiff puppy for sale, you should purchase one from a reputable breeder. Trust a reliable breeder that can give you the health history of the mother and father dogs. This may be hard to find at first, but trust me, they are out there. Avoid puppy mills at all costs.
