Shar Pei
The Shar Pei is a short-coated medium-sized breed of dog, renowned for its excessively wrinkled skin. The breed resembles many dog breeds from the mastiff family; however, it is most closely related to spitz breeds, with the Chow Chow being its closest relative. This is most clearly seen with the two breeds both possessing unique blue-black tongues. This dog falls within the same genetic group as the Chow Chow, the Akita, and the Shiba Inu.
