The Chow Chow is an ancient spitz-type dog from northern China, where it worked as an all-purpose hunter, guard, herder and puller. It's a square, heavy-boned medium dog, usually 45 to 70 pounds and 17 to 20 inches tall, with a lion-like ruff, a scowling expression, a blue-black tongue and either a rough or a smooth double coat.
Chows tend to be dignified, independent and deeply attached to a small circle of people, while staying aloof with strangers. They need early socialization and calm, consistent training, and the heavy shedding means regular brushing. Plenty of Chows are quiet and clean indoors, but each dog differs, so adopters who prize a self-possessed companion over an eager-to-please one usually appreciate the breed most.
