The Great Pyrenees is a capable and imposing guardian, devoted to its family, and somewhat wary of strangers—human and canine. It is often used to guard livestock. When not provoked, it is calm, well-mannered and somewhat serious. Courageous, very loyal and obedient. Gentle and affectionate with those he loves. Devoted to family even if self-sacrifice is required. It is very gentle with its family and children. It does best with children when it is raised with them from puppyhood, and if it is not being used as a working flock guard be sure to socialize it well with people, places and noises.
These dogs are not recommended for apartment life and would do best with a mid-to-large sized yard. They need space, but adapt well to family life. They are not really active indoors, but need regular exercise outdoors. A fence is a must as they may wander away in search of the borders to what they believe is their territory.
