What Is the History of Pyrenean Mastiffs?
Pyrenean mastiffs have been around since the Middle Ages. While their exact origins aren’t known, they come from the mountains that border Spain and France. This was known as the Kingdom of Aragon, which is where some of the first Pyrenean mastiffs came around.
From there, the breed came and went during times when sheep and other types of cattle needed protection from wolves and other types of animals. It wasn’t until 1977 that a breed club was created for this breed, which is the Club del Mastín del Pirineo.
Back in the day, Pyrenean mastiffs were used to protect cattle from predators. What’s more, they were loyal farm dogs that used to protect crops from smaller predators that wanted to get at the land.
Today, the Pyrenean Mastiff Club of America (PMCA) represents the breed in the United States and it was formed in 1996. Still, these dogs have become more popular and you can find the breed from many breeders in the United States.
What Do Pyrenean Mastiffs Look Like?
Pyrenean mastiffs have a distinct appearance that resembles a Saint Bernard and a great Pyrenees. In fact, they look like a mix of these two breeds, so it’s not uncommon for them to be massive dogs.
They’re one of the largest breeds around and sport a thick double coat that makes them look even larger. Their coats can be a wide range of colors including blue, black, brown, golden, red, or even shades of gray. Ultimately, it depends on the dog’s parents.
Pyrenean mastiffs have muscular bodies and strong-looking heads that complement their massive build. On the sides of their face, they have loose jowls that give them a droopy-like appearance below the snout.
Additionally, their ears are floppy and their faces have some wrinkles, so their face looks pretty droopy overall. However, one unique trait is that their ears will lift up at times to listen for noises or potential threats.

Pyrenean mastiffs have wavy or wiry coats, but it may look straight from a distance.
What Is a Pyrenean Mastiff’s Temperament?

That said, when you bring them into your home and give them the proper training, Pyrenean mastiffs become gentle giants.

Are Pyrenean Mastiffs Easy to Train?
Pyrenean mastiffs are easy to train. They were bred to take care of other animals and people on large plots of land, so it’s not surprising that they will respond to training. You can teach them many commands and train them for specialized roles like service dog work or watchdog work.
Are Pyrenean Mastiffs Good Watchdogs?

Pyrenean mastiffs are also okay for mental health disabilities. They’re not the best at this job but can be taught to remind someone when it’s time for medication or they can function as a guide through crowds for people who have social anxiety.
Pyrenean mastiffs may also be therapy dogs or emotional support animals. Their efficiency in these areas depends on your needs and housing situation. For example, if you live in a small apartment it’s not wise to get a Pyrenean mastiff as an ESA.
On the other hand, they’re large enough to comfort large groups of people in hospice care, funeral homes, and schools.
How to Care for a Pyrenean Mastiff?
Pyrenean mastiffs have a lot of grooming and health needs that you need to be aware of. While you don’t have to do a lot of maintenance on them, what gets you is how many things you have to do.
Unlike other dogs, for example, you need to clean their ears and trim their dewclaws. This can be labor intensive when you pair it with brushing their coat three days per week in an attempt to keep up with their shedding.
Aside from grooming, it’s important to feed Pyrenean mastiffs a balanced diet and help them exercise. If you’re not seeing enough movement it doesn’t hurt to take them on a walk. The last thing to note is that you need to keep an eye on health problems with regular vet appointments.
Do You Need to Groom a Pyrenean Mastiff?
Pyrenean mastiffs need to be groomed often. Brush that coat at least three times per week and give them a nice warm bath at least once a month. Brushing their coats and bathing them reduces the amount of shedding and matting that develops in their coats.
You also need to keep an eye on their claws and trim them if they’re not grinding down naturally. We recommend taking them to a professional when you need to trim their dewclaws. As for their teeth, brush them about twice per week and check their ears and jowls for infections or irritation.
Do Pyrenean Mastiffs Shed?
Pyrenean mastiffs shed a lot. They shed throughout the year but they also have a double coat that begins to shed frequently during the spring and fall months. If you don’t brush their coat or give them a trim, you’ll have hair all over the place in your home.
What Health Problems Do Pyrenean Mastiffs Have?
Pyrenean mastiffs are healthy dogs but that doesn’t mean they’re invincible. As they age, there are a few health risks you have to keep an eye on. These include:
- Hip Dysplasia: A condition that results in the hip joint not forming properly, which causes pain and discomfort
- Panosteitis: Inflammation of the long bones in the leg of the dog, which is common in big breeds like Pyrenean mastiff
- Eye Conditions: Cataracts and other eye degeneration diseases
In addition, you’ll also want to watch out for bloating and problems with the jaw. To avoid these health problems, it’s important to consult with a vet as they get older. Take your Pyrenean mastiff for yearly checkups to stay ahead of these problems.
How Long Do Pyrenean Mastiffs Live?
Pyrenean mastiffs live for a long time compared to some other large dog breeds. On average, expect them to live for 10 to 12 years. To keep them around for a long time, take them to the vet often and feed them a healthy diet.
While they’re not the most energetic dog, make sure they get plenty of exercise to keep them healthy as well. Failing to do so can result in obesity and other health conditions that reduce their lifespan.
What Should a Pyrenean Mastiff Eat?
Pyrenean mastiffs should eat a diet that’s high in protein and clean ingredients. Food needs to be specifically formulated for large dogs and it doesn’t hurt to include some whole foods like chicken, beef, and other types of meat. Still, keep their diet at around 30% protein when possible.
When it comes to the amount of food, they’re big dogs so they need a lot. Feed them about 6-10 cups of dry food per day. You can feed them in two separate meals if you want to split their food intake up. As for young puppies, split their meals into several meals throughout the day to avoid rapid weight gain and gorging.
Pyrenean mastiffs need vitamins too, so include supplements like glucosamine and chondroitin if the food you feed them doesn’t contain them.
Is a Pyrenean Mastiff the Right Dog for Me?
The Pyrenean mastiff is a great fit for many types of people but you need to consider your living situation and the amount of space you have. These dogs are not suitable for small apartments because of their size and they do the best in environments that give them plenty of space to graze and interact with their environment.
That said, as long as you have the space you shouldn’t have to worry about a Pyrenean mastiff. They’re great for children of all ages and won’t bother any other household pets. However, if you hate shedding and drooling you’ll want to opt for a different dog breed. Plus, their grooming can be a lot to keep up with if you fall behind or don’t have the time.
After you consider these factors, make sure you adopt a Pyrenean mastiff from a reputable breeder to avoid potential health and behavior problems.
