The Chinese Crested Dog is a hairless breed of dog. Like most hairless dog breeds, the Chinese Crested Dog comes in two varieties, with and without fur, which are born in the same litter: the Powderpuff and the Hairless. One famous Chinese Crested Dog was the Hairless purebred named Sam. He was the winner of the World's Ugliest Dog Contest from 2003 to 2005; he died before he could compete in 2006. Other Chinese Crested Dogs, either purebreds or mixes, have finished high in the event as well. 6 In popular culture. Japanese Chin.
