Which breed of dog is now extinct: Chinese Crested Dog or the Chien-gris?
Chien-gris The Chien-gris a.k.a. Gris de Saint-Louis ("Grey St. Louis Hound") 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 (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.
Bonobo The bonobo ( or ; "Pan paniscus"), formerly called the pygmy chimpanzee and less often, the dwarf or gracile chimpanzee, is an endangered great ape and one of the two species making up the genus "Pan"; the other is "Pan troglodytes", or the common chimpanzee. Although the name "chimpanzee" is sometimes used to refer to both species together, it is usually understood as referring to the common chimpanzee, whereas "Pan paniscus" is usually referred to as the bonobo.
