Shar Pei

Ancient "Wrinkled" Breed from China

With its distinctive wrinkles, triangular ears, hippopotamus-shaped muzzle and blue-black tongue, the Shar-Pei is easily recognizable.

The dog breed also has some other notable distinctions: Named as the world's rarest dog breed by Time Magazine and the Guinness Book of World Records in 1978, the Shar-Pei is also one of most ancient dog breeds, as determined by DNA analysis.

However, most Shar-Pei owners will tell you that they value their dogs more so for their devotion, loyalty and affection.

As with any pet, be sure to regularly consult a veterinarian for routine care and medical advice for your four-legged friend.
