A serious, well-behaved, devoted, and calm breed, the Great Pyrenees makes for a superb guard, often jeopardizing their own well being to protect their charge. They are great with children and have a boundless love for their family. They can be wary of strangers due to their background as a guard dog, and should be socialized if they are going to be in a home with other pets. Since they are such a smart, dedicated breed, they can often be difficult to train unless their owner shows a decidedly dominant demeanor. .
