The Great Pyrenees is a French and Spanish mountain livestock guardian, known in France as the Patou. Shepherds trusted these giant white dogs to stay with flocks through the night and face down wolves and bears, which explains the size, the weatherproof double coat and the plumed tail. Adults commonly weigh 85 to 120 pounds, and the white or white-and-marked coat sheds heavily.
That job history shapes the personality. Many Pyrs are calm and devoted at home, yet they think for themselves, take cues slowly and patrol after dark with a deep bark. In Mobile, that means a securely fenced yard, a leash anywhere else and a plan for the hot, wet months. Pyrs and Pyr mixes vary, so each dog's own manner matters more than the label.
