Shar Pei

Dog

The Shar Pei, or Chinese Shar-Pei, is a breed of dog known for its distinctive features of deep wrinkles and a blue-black tongue. The breed comes from China. The name 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 wrinkles loosen and spread out as they "grow into their skin".
