Pyrenean Mastiff
Other names: Navarra Mastiff

The Pyrenean Mastiff is a large, imposing dog. Although they have huge, barrel-like frames, the Pyrenean Mastiff is very quick on its feet. These dogs are also completely fearless; they were first bred to protect livestock from wolves and beers. Despite their intimidating stature, the Pyrenean has a soft, loving, and even docile nature when it's not on guard duties. These gentle giants form really strong bonds with their owners and enjoy being around young children. Pyrenean Mastiffs don't require massive amounts of exercise, but they do need lots of space to feel comfortable.
Key facts about the Pyrenean Mastiff
Origins and history
The Pyrenean Mastiff was developed in the Aragon and Castilla regions, which we now know as modern day Spain. These large, courageous dogs protected livestock and fought off bears and wolves in the process. Unsurprisingly, they became a popular choice for farmers and herders in and around the Pyrenean mountain ranges. They remained popular until the outbreak of the Spanish civil war. Given the hardships many people faced, the Pyrenean Mastiff was simply too expensive to take care off, and their numbers began to decline. Luckily for modern-day dogs lovers, a group of breeders started to re-establish the Mastiff during the 1970s. It was then recognised by the International Federation of Kennel Clubs (FCI) in 1982.
