Which breed of dog is now extinct: Chinese Crested Dog or the Chien-gris?
Chinese Crested Dog The Chinese crested dog is a hairless breed of dog. Like most hairless dog breeds, the Chinese crested comes in two varieties, with and without fur, which are born in the same litter: the Powderpuff and the Hairless.
Toy Bulldog The Toy Bulldog is an extinct dog breed that existed in England at 18th and early 19th centuries. Breeders were working in two different directions to create this breed. One was to downsize the Bulldog. This was not very successful due to complications with breeding sub-regular size dogs of this breed together. The dwarf size Bulldog puppies were and still are occasionally born out of regular size parents, but they were neither the healthiest, nor the most fertile dogs. They often produced regular-size puppies. Thus, this version of the breed had never been established.
