Document 6: Bone-mouth: Bone-mouth or Guzui (骨嘴, pinyin: "gǔ zuǐ"), literally means Bony Snout in Mandarin Chinese, is the original type of the Shar Pei dog breed. There are two varieties in Shar-Pei: a traditional type with fewer wrinkles, roof-tile muzzle, pointed tail, short hair (sandpaper coat), and a modified heavier muzzle (hippopotamus look) with meat padding on top and longer hair (brush coat). Breeders in China (particularly in Southern China, Hong Kong, Macau) commonly called the traditional type found originally in Dali (Dailek, Dailet), Namhoi City in Guangdong Province as the Bone-mouth (Bony-snout) because of its dry type of muzzle, and the latter development in the Western world as the Meat-mouth (Meaty-snout) because of its meaty type of muzzle with loose skin.

Document 7: Lithuanian Hound: The Lithuanian Hound has been traditionally used to hunt hare, fox, and boar. The breed is mentioned in the Statutes of Lithuania (16th century). It is believed that it comes from the mixing of bloodhounds with several other hound breeds. Once a popular breed in Lithuania, the population decreased to 78 individuals after World War II. Thanks to several enthusiasts, the hound was revived, standardized, and the number of registered and documented dogs reached around 350 in 1987. After the dissolution of the Soviet Union, the breed decreased to around 150 individuals by 1998. The decrease in popularity is explained by changing hunting habits: the Lithuanian Hound is best suited for hunting large animals in large open areas, but modern hunting plots are decreasing in size. The Lithuanian Cynological Society plans to register the breed with the Fédération Cynologique Internationale (FCI).
Document 8: 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.

Document 15: Skinny pig: The Skinny Pig is an almost hairless breed of Guinea pig. Skinny pigs typically have hair on their muzzles, feet, and legs, but are hairless over the remainder of their bodies. Some of them have a thin covering of fuzzy hair on their backs as well. A healthy Skinny has skin that is mostly smooth with some wrinkling around the legs and neck, the body is full with no appearance of spine or ribs. Skinnies can come in a variety of colours and patterns, such as Dutch, Tortoiseshell, Himalayan and many others. "Skinny" is the term used for hairless guinea pigs to describe the illusion of their visually thinner appearance, or coloquially referring to the exposed skin of the animal. The modern Skinny Pig breed originated with a cross between haired guinea pigs and a hairless lab strain. The hairless strain that it is most likely related to was a spontaneous genetic mutation that was first identified at Montreal's Institute Armand Frappier in 1978, in a colony of Hartley lab guinea pigs. In 1982 they were sent to Charles River Laboratories to be bred for laboratory use and are commonly used in dermatology studies today. They are an outbred strain that has an intact thymus and normal immune system.
