The Chongqing dog (Chinese:重庆犬 ) is an ancient mastiff Tugou historically used for hunting and guarding in Chongqing, China. Today this breed is prized as a fearless and tough protector of their family and home. The term 'Chongqing Dog' may also be used to refer to the Chuandong hound. Both dogs share a common foundation stock and are part of the Tugou. Chongqing Dogs are medium sized with compact muscular bodies. Their tail should be short and held upright, often described as a 'bamboo stick'. Their hair coat is short, course and reddish-brown or black in color. They have a blue-black tongue, prominent stop and square head. Their ears are naturally pricked, and not cropped. (Source: Wikipedia.org, CC BY-SA)
