More: Yuri the Great Pyrenees loves to guard his "herd" (family), barking day and night to ward away the local bears, coyotes, fox, squirrels, chipmunks, butterflies, and the occasional delivery person. When his job is done, he loves to go on excursions and sometimes thinks he's a lap dog. He often gets invited to visit the dog sitter to help entertain her other guests!
