Xiasi Dog (Chinese: 下司犬)[1] or Lower Division Dog is a breed of tugou named after the village of Xiasi, Guizhou Province in China where they have been raised by the Miao people for thousands of years.[2][3] Historically bred as a hunting dog and watchdog, the Xiasi Dog is prized today for bringing wealth to the family.[1][3] Today the breed is critically endangered with low genetic diversity and an estimate of only 270 purebred Xiasi left.[2][4] Xiasi Dogs are now accepted in most Chinese dog shows.
