or chow
Breed of dog that shares with the shar-pei an unusual blue-black tongue.
The chow chow originated in China and dates to the Han dynasty (206 BC–AD 220); it may be one of the oldest of all dog breeds. It is compact and has a large head and a thick coat that forms a dense ruff about the neck. The coat is evenly coloured, either reddish brown, black, or blue-gray. The adult stands about 18–20 in. (46–51 cm) tall and weighs 45–70 lb (20–32 kg). The breed is usually loyal to owners but aloof with strangers.
