The Chow Chow is a spitz-type of dog breed originally from Northern China. The Chow Chow is a sturdily built dog, square in profile, with a broad skull and small, triangular, erect ears with rounded tips. The breed is known for a very dense double coat that is either smooth or rough. The fur is particularly thick in the neck area, giving it a distinctive ruff or mane appearance. The coat may be shaded/self-red, black, blue, cinnamon/fawn, or cream.
Originally developed in Northern China, the Chow Chow was used for hunting, guarding, and pulling carts.
The Chow Chow is often recognized by its unique blue-black tongue and lion-like mane. They tend to be very loyal to their family but can be aloof and reserved with strangers. Early socialization and training are essential due to their independent nature.
