Shar Pei
The dog breed Shar Pei originated in China and has the distinctive features of deep wrinkles and a blue-black tongue. The name (沙皮, pinyin: shā pí) translates to "sand skin," not because of color but because of texture. As puppies, Shar Pei have lots of wrinkles, but as they mature, the wrinkles disappear as they "grow into their skin".
Appearance
Shar Pei come in many colors but have the same characteristic blue-black tongue of the Chow Chow. Superabundant loose skin and wrinkles cover the head, neck, and body of puppies, but adult Shar Pei should grow into their skin so that these features are limited to the head, neck and withers. Improper breeding (detrimental to the health of the Shar Pei) produces adult dogs with wrinkles all over the body. Small ears, a hippo muzzle shape, and a high set tail also give the Shar Pei a unique look
