Pyrenean Mastiff

The highly intelligent Pyrenean Mastiff, originally a mountain dog from the Spanish Aragonese Pyrenees, is often confused with its close cousin the Pyrenean Mountain Dog or the St Bernard. Generally calm and gentle, this huge dog is a loving and devoted pet, and is also an excellent guard dog.
