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.
Tweed Water Spaniel The Tweed Water Spaniel, or Tweed Spaniel, is a breed of dog extinct since the 19th century. It is best known for being involved in the early development of the modern Curly Coated Retriever and Golden Retriever breeds of dogs. They were described as a generally brown athletic dogs from the area around Berwick-upon-Tweed near the River Tweed and close to the Scottish Borders. A type of water dog, the breed was not well known outside the local area. This breed may have been created by crossing local water dogs with imported St. John's water dog, another breed which is also now extinct.
