The Miniature Shar Pei or Mini Pei is a breed of dog with slightly smaller proportions than the larger Standard Shar Pei.
 They have been bred to be smaller in size through a recessive gene carried in their DNA.
 The reduced size of this breed creates a versatile dog that is unique yet small, making for a good family companion.
Conformation in dogs refers solely to the externally visible details of a dog's structure and appearance, as defined in detail by each dog breed's written breed standard.
 A dog that "conforms" to most of the items of description in its individual breed standard is said to have "good conformation".
 Unlike equine conformation, there are no fixed rules for dog conformation, as dogs are the most variable in appearance of any animals ("Phenotypic variation among dog breeds, whether it be in size, shape, or behavior, is greater than for any other animal").
 Instead, conformation in dogs is based on the dog type from which the breed developed, along with many details that have been added to the breed standard for purposes of differentiation from other breeds, for working reasons, or for enhancing the beauty of the animals from the viewpoint of the fanciers who wrote the breed standards.
Shar Pei fever (also called familial Shar Pei fever or FSF) is a condition seen in Shar Pei characterized by recurring fever and swelling of the hocks.
 It is similar to familial Mediterranean fever in humans.
 The cause is unknown, but it is thought to be inherited.
 Shar Pei fever can result in renal and liver failure through accumulation of amyloid in those organs (amyloidosis).
Vulnerable Native Breeds are a group of dog breeds originating in the United Kingdom and Ireland, and identified by The Kennel Club (KC) as having annual registration numbers of 300 puppies or fewer.
 The need for such a list was first identified in June 2003, with research conducted by the KC to identify the extent of the vulnerability and viability of each breed.
 It was a joint project, with the KC working with the British and Irish Native Breeds Trust, later to be known simply as the Native Dog Breeds Trust.
 The breeds on the list have been promoted at events such as Discover Dogs and Crufts, and by asking that owners of these breeds mate their dogs rather than having them spayed.
The Chinese Shar-Pei, is a breed of dog known for its distinctive features of deep wrinkles and a blue-black tongue.
 The breed originates from Canton, China.
 The English name (沙皮, pinyin: "shā pí"; probably derived from British spelling of the Cantonese equivalent, "sā pèih") translates to "sand skin" and refers to the texture of its short, rough coat.
 As puppies, Shar Pei have numerous wrinkles, but as they mature, these loosen and spread out as they "grow into their skin".
 Shar Pei were named in 1978 as one of the world's rarest dog breeds by "TIME" magazine and the "Guinness World Records".
 Although the Shar Pei has been identified as a basal breed that predates the emergence of the modern breeds in the 19th century, the American Kennel Club did not recognize it as a breed until 1992.
The Rastreador Brasileiro (in English, Brazilian Tracker) is a large breed of dog from Brazil, first recognised by the Fédération Cynologique Internationale in 1967, but an outbreak of disease, compounded by an overdose of insecticide, wiped out the breed's entire breeding stock.
 The FCI and the Brazilian Kennel Club (Confederação Brasileira de Cinofilia) then declared the breed extinct in 1973 and delisted it.
 Since then, efforts have been made to re-create the breed.
 The Rastreador Brasileiro is a hunting dog of the scenthound type.
 The breed is also known by the names "Urrador" (for its hunting cry) or "Urrador Americano", in reference to the American (U.S.) coonhounds in its background.
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.
 Sharpei Club Hong Kong based its breed standard on the traditional bone-mouth standard.
 This Bone-mouth wiki refers to the standard of Sharpei Club Hong Kong, formerly known as F.C.I. standard 309/1994.
Tugou (土狗, pinyin: "tǔ gǒu"), literally means Native Dog in Mandarin Chinese, is the general name for several dog breeds originated from China and still abundantly exists across the country today.
 Tugou includes the most popular Chinese dog breed - the Chinese Field Dog (, pinyin: "zhōng huá tián yuán quǎn"), Chinese Chongqing Dog, Xiasi Dog, and several other native dog breeds distributed across China.
 They are roughly 45–50 cm tall at the shoulder.
A breed group is a categorization of related breeds of animal by an overseer organization, used to organize the showing of animals.
 In dogs, kennel clubs define the "Breed Groups" and decide which dog breeds are to be included in each breed group.
 The Fédération Cynologique Internationale breed groups are used to organize dogs for international competition.
 Breed groups often have the names of, and are loosely based on, ancestral dog types of modern dog breeds.
Dog breeds are dogs that have relatively uniform physical characteristics developed under controlled conditions by humans, with breeding animals selected for phenotypic traits such as size, coat color, structure, and behavior.
 The Fédération Cynologique Internationale recognizes over 400 pure dog breeds.
