We were looking for a giant breed dog with relatively few health issues and a fairly decent life span for its’ size and the Pyrenean Mastiff fit that description. I had some hesitation in buying a Livestock Guardian Dog as a house pet but seven months on, I realize that I shouldn’t have thought twice about it. Even-tempered and calm is how I would best describe ours. He is as smart as a whip and has been easy to train as long as I get up each morning and look in the mirror and repeat the mantra, “I am the alpha dog.” He has quickly picked up the do's and don’ts although he is mischievous enough to see if I am paying attention. He is wonderfully gentle with very young children and small animals, non-plussed by thunder and not terribly bothered if he is left alone. Three words to describe him? Content, gentle & affectionate. Advice if you are considering the breed - socialization and training - never let them believe you are anything but the boss.
