 Originating from Spain, the Pyrenean Mastiff, or Perro Mastin del Pireneo, is a large flock-guarding breed developed for fighting off predators of sheep such as bear and wolf. The breed is rather large, reaching 34 inches in height, and weighing up to 175 lbs. They have medium length fur in the form of a good coat, but not nearly as profuse as the Great Pyrenees Dog. Pyrenean Mastiffs are very calm and have a kindly disposition. They are fine with other animals and dogs, as long as their family or property is not threatened. If property is threatened, the Pyrenean Mastiff can become very dreadful to whoever is endangering his property. It has been said about the Pyrenean Mastiff that he has a "clear concept of his strength". They can be very brave when it comes to defending their own. But with family and friends, this Mastiff is docile and friendly. An excellent guard as well as a calm and sweet friend, the Pyrenean Mastiff can make a home more secure as well as joyous at the same time. 


 The Pyrenean Mastiff is meek, docile and extremely intelligent. Pyrenean Mastiffs are very brave and fierce with strangers. They show extreme benevolence with other dogs knowing of its strength. Should a threat arise, the Pyrenean Mastiff is skilled at fighting, remembering its acquired behavior in the fight with wolves. They have a deep and intense bark, but are usually quiet. Pyrenean Mastiffs know their strength and they know how to use it, so they make very good guard dogs. They are protective of their own, kind with family and friends, and friendly when "off-duty". They are reliable, good around children, as well as good with other pets. They will not threaten another without reason, and are mostly a gentle but brave breed. 


 Half long, thick and laying flat to the body, the ideal medium length will be of 6 to 9cm at the middle of the back and longer at the shoulder, neck, stomach and behind hind and forelegs, as well as in the tail panache. Never woolly. The coat should be brushed every week and you should check to make sure nothing gets stuck in it, as it can get dirty easily. Nails, ears, and teeth should always be checked and/or trimmed routinely. 


 Eye problems, inflammatory bowel disease, and bloat. Bloat is a health issue common to most dogs, being the largest killer of dogs only second to cancer. Breeds with deep chests often suffer from this condition. Another health concern for Pyrenean Mastiffs is a low incidence of hip dysplasia. 


 Because of their massive size, the Pyrenean Mastiff needs adequate exercise in an environment that can handle his size! Outdoor daily walks are good for this breed, and they should be kept in good shape with consistency. 


 The Mastin del Pirineo is a very trainable breed, and will obey "from day one", as some owners have stated. They are excellent in learning and very intelligent. They should be trained as puppies, and always use positive reinforcement.
