You’ve likely heard of the Shar-Pei, an adorable and ancient Chinese dog breed that goes back more than 2,000 years. But did you know they are the world’s most wrinkly dog? The Shar-pei has wrinkles and rolls that cover their whole body. Though they look like they’re meant purely for cuddles, these loyal dogs are actually hard-working and strong, and best suited to an experienced owner. They were originally used as a rugged hunting, herding, and guardian breed. The phrase shar-pei literally translates as “sand skin” thanks to the sandpapery feel of their short, dense coat!
