As grand and wondrous as the Pyrenean mountains whence he comes, the Pyrenean Mastiff is an awe-inspiring guardian dog that remains one of Spain's best kept secrets. The Pyrenean Mastiff is rugged enough to weather extremes of climate, though he prefers to be indoors with his family, to whom he is fiercely devoted. Towering over 32 inches at the shoulder, the adult Pyrenean Mastiff offers expert protection for home and property, given his fantastic bravery and natural aloofness to strangers. Owners prize this noble breed's calm, confident demeanor and its superior intelligence and affectionate temperament.
