The Chinese variety of Shar Pei looks like a Doberman Pinscher with small floppy ears, long legs, and a narrow face. Coming in many colors, it has the same characteristic blue-black tongue of the Chow Chow. The wrinkles are seen only on the face and back. Through selective breeding, the American variety of Shar Pei has very short, stubby legs, many wrinkles covering all of its body, and a wide "hippo face". The tail curls up and rests on the back.
