The Chow Chow is a stocky dog with broad skull and small, rounded ears. The breed has a very dense coat that is either smooth or rough. The fur is particularly thick around the neck, giving the distinctive ruff or mane. The coat may be one of several colors including reddish-brown (described as "red"), black, blue, cinnamon, cream, or white. Not all these color varieties are recognized as valid in all countries.
