The Great Pyrenees is said to be one of the least aggressive of the livestock guardian dogs (LGD), and gains acceptance from her flock by being initially submissive. A ewe or ram may “posture” by head butting, but typically, the Pyr responds by crouching down. Seeing that the dog isn’t a threat, the sheep readily accept the dog. That said, a Great Pyrenees will submit to livestock, but not other canines, and certainly not to wolves, coyotes and dog packs which are vigorously challenged and driven off. Great Pyrenees owners, show us your dogs!
