One of the puppies fathered by the world's first cloned dog Snuppy is seen at Seoul National University's College of Veterinary Medicine in Seoul September 5, 2008. The cloned dog Snuppy, an Afghan hound, impregnated two dogs through artificial insemination to produce 10 puppies, which were born in May. Snuppy was produced in 2005 by a lab once headed by Hwang Woo-suk, who fell from grace after two of his papers on cloning human embryonic stem cells were found to be based on fabricated data. Independent testing proved that Snuppy was cloned. REUTERS/Jo Yong-Hak (SOUTH KOREA)
