The Chow Chow (sometimes simply Chow) is a dog breed originally from northern China, where it is referred to as Songshi Quan (Pinyin: sōngshī quǎn 鬆獅犬), which means "puffy-lion dog". 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 Foo dog, 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. The Chow is a unique breed of dog thought to be one of the oldest recognizable breeds. Research indicates it is one of the first primitive breeds to evolve from the wolf. Recent DNA analysis confirms that this is one of the oldest breeds of dog that probably originated in the high steppe regions of Siberia or Mongolia, and much later used as temple guards in China, Mongolia and Tibet.
