This gorgeous breed is of Chinese origin and is known for its black tongue and thick mane, which give it a leonine appearance. The Chow Chow was initially used as a guard dog and hunter but became popular as a pet during the early 19th century. The Kennel Club classifies Chows as large utility dogs. They tend to be social and outgoing, but without proper training, they can be unfriendly towards people and other dogs. That’s why every Chow Chow on our books is strictly trained in obedience.
