This one might be considered rude, but my dad and I think it's funny. The Shar Pei is the super wrinkly dog, and what kind of people have wrinkles? Elderly people. Like I said, funny, but maybe mean...
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". Shar Pei were named in 1978 as one of the world's rarest dog breeds by TIME magazine and the Guinness World Records. The American Kennel Club did not recognize the breed until 1991.Small, triangular ears, and a high-set tail also give the Shar Pei a unique look. For show standard, "the tail is thick and round at the base, tapering to a fine point" (AKC standard February 28, 1998). As puppies, Shar Peis are a lot more wrinkly than adults and, although some adults can be wrinklier than their puppy self, an adult pei should have wrinkles mostly on the face, a few on their shoulder and at the base of the tail. A muzzle shaped like hippopotamus (hippo). Their pigmentation resemble the Chow Chow as they've been crossed before, probably giving them the same blue-black tongue. There are over sixteen recognized colors in AKC. The coat must be solid in color, and any Shar-Pei with a "flowered coat" (spotted) or black and tan in coloration (i.e. German Shepherd) is a disqualification. Colors include black, blue, cream, fawn, red-fawn, red, sable, apricot, chocolate, and isabella. The nose may be black or brick (pink with black), with or without a black mask. A Shar-Pei can also have what is called a "dilute" coloration. Meaning the nose, nails and anus of the dog is the same color as the coat, (i.e. chocolate coat with chocolate nose, and nails). All of these color variations are acceptable and beautiful, but the coat color must be solid and well blended throughout the whole body of the dog.
