The Chow Chow is an ancient spitz from northern China that worked as a hunting, guarding, herding and pulling dog. Today it's a square, heavy-boned, medium-sized dog, usually 45 to 70 pounds, with a lion-like ruff, a scowling expression and a blue-black tongue. The coat is either rough and offstanding or short and smooth, but both are double coats that shed heavily.
Chows tend to be dignified, independent and quiet indoors, with a strong attachment to a small circle of people. They dislike rough handling and usually need early socialization and calm, consistent training. In San Bernardino, that also means brushing several times a week, more during seasonal sheds, and keeping a close eye on the thermometer, since a dense coat and dry valley heat are a difficult mix.
