Pyrenean Mastiff originated in the Pyrenees Mountains of Spain, where it protected livestock, primarily sheep, from wolves, bears, and poachers. The Pyrenean Mastiff dog breed dates back to the Middle Ages.
The Pyrenean Mastiff is a massive dog, standing 28 to 32 inches tall, although there is no established maximum height. These dogs weigh 120 to 155 pounds or more. The head is large and moderately long, the eyes are small and dark, and the ears are medium-sized and dropped but mobile. The body is longer than tall, with a wide chest. It has double dew claws. The tail is held in a saber shape and reaches the hocks. The coat is about 3 inches long and is always white with colour around the eyes and ears. There may be patches of colour on the body as well. The coat requires thorough brushing at least twice a week. These dogs shed heavily twice a year, so additional brushing will be needed.
A good daily walk or even a hike on a trail following an owner on horseback is all fun to this dog breed. It is not a high-energy breed, but if young dogs are left to their own devices without a good walk to use up energy, they may find their own mischief. The Pyrenean Mastiff breed is very receptive to training; consistency and gentle discipline are the keys to training these dogs.
The Pyrenean Mastiff breed matures more slowly than many other dog breeds, so trainers must be patient. The Pyrenean Mastiff is also a very protective watchdog and guardian, so socialisation should begin very young and continue into adulthood. This breed may be too much for most first-time dog owners. The Pyrenean Mastiff needs her owner to be a leader, and the dog needs to spend time with her owner. Even though this is a livestock guardian, the Pyrenean Mastiff also needs companionship. The Pyrenean Mastiff is good with kids and other dogs but is very watchful of strange dogs and people. Most of these dogs drool. The primary health concern is hip dysplasia.
