The Great Pyrenees is a livestock guardian from the mountains between France and Spain, where big white dogs stayed with flocks and watched for wolves, bears and thieves. Adults stand 25 to 32 inches tall and typically weigh 85 to 120 pounds, with a thick white double coat that may carry gray, tan or reddish-brown markings.
That background explains the Pyr you meet today: calm and affectionate at home, but independent, protective and inclined to bark at night. In Greenville, where dogs must be leashed off their owner's property and excessive barking can draw neighbor complaints, those traits take planning. Pyrs and Pyr mixes also show up often in shelters, so the dogs listed here may vary in size and coat.
