The breed has also been called the Tang Quan, "Dog of the Tang Empire." It is believed that the Chow Chow is one of the native dogs used as the model for the Chinese guardian lions, the traditional stone guardians found in front of Buddhist temples and palaces. It is one of the few ancient dog breeds still in existence in the world today.
