Chongqing dog is a rare and old breed of dog that is believed to have first appeared 2,000 years ago during the Han Dynasty in southwestern China. It possesses a short, "bamboo stick" tail and a reddish-brown coat.

The direct ancestors of the Chongqing dog are the native breeds from the regions adjacent to Chongqing, these being Dazhu, Hechuan, Yongchuan, Lingshui and Guanan, and these are collectively known as "Chongqing Dog". The Chongqing dog was developed for hunting in the mountains of East Sichuan.^[2] Due to urbanisation they lost their major purpose so their population declined rapidly. However, the breed was restored in the 1970’s and have become a popular utility dog since.
