The Chien-gris aka Grey St. Louis Hound (Gris de S.Louis) was a breed of dog, now extinct, which originated in Medieval hunting times. Like the Bloodhound it was a scenthound, and formed part of the royal packs of France, which were composed, from about 1250 till 1470, exclusively of hounds of this type. According to King Charles IX of France, (1550–1574) they supposedly were introduced to France through Louis IX of France (i.e. King Louis IX, 1226–1270), who had encountered these hounds while a prisoner during the Crusades, and subsequently received some as a gift. Old writers on hunting liked to ascribe an ancient and remote origin to their hounds, and these were claimed to be originally from Tartary. They were large, and, even though they did not have such good noses, were preferred by the Kings to the St Huberts, which were said to be only of medium size.Jaques du Fouilloux, in the 16th century, says they were common, and describes them as ‘gris’ (grey) on the back with forequarters and legs tan or red, some having near black hair on the back. They were rough haired, and were ancestors of the modern French rough-coated Griffon breeds. However the rough coats were not mentioned by Charles IX or du Fouilloux, and it has been suggested they were acquired later through interbreeding with indigenous French hounds. They were headstrong, wide casting hounds, inclined to change or overshoot, but determined in their pursuit of a quarry to the death. However, by the nineteenth century, like the St Hubert, they had become virtually impossible to find, because of mixed breeding and the effect of the French Revolution on French hunting.George Turberville translated du Fouilloux’ book on hunting into English, and used the term ‘Dun hound’ to translate ‘Chien-gris’. We may presume he did not translate it literally as ‘grey-hound’ to avoid confusion. One finds the term ‘dun-hound’ in some subsequent writing in English, suggesting that the kind also existed in Britain, and it has been supposed that these ‘dun-hounds’ went into the make up of the Bloodhound, accounting for the ‘badgering’ of the hair in the saddles of some bloodhounds. However, Turberville did not make it very clear that his book was a translation, and it is highly possible that people mistakenly believed his work was about English hunting. Early references to the dun-hound may simply come from people relying, like Nicolas Cox, on Turberville, and it is quite possible that the dun hound was never a significant animal in British hunting.

The Chinese Chongqing Dog is a rare breed of dog native to the Chongqing city of China, somewhat like a bulldog-Thai ridgeback mix (not, however, descended from either of these) but with a distinct tail, color, and coat. In its early years, it was used for hunting wild boar and rabbits, but it’s now used in China to protect families and belongings. They are an ancient, natural breed said to have existed for 2,000 years since the time of the Han Dynasty in Ancient China. After the establishment of the People’s Republic of China in 1949, the breed’s numbers were greatly reduced, and only people in rural communities still kept it; the breed is still rare, even in China.
