The Chien-gris a.k.a. Gris de Saint-Louis was a breed of dog, now extinct, which originated in Medieval times. Like the Chien de Saint-Hubert 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, (1550–1574) they supposedly were introduced to France through Saint Louis, 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.
