Dogs cloned from world's 1st cloned dog complete 7 years
US and South Korea-based researchers had cloned Snuppy, the world's first cloned dog produced from an Afghan hound named Tai in 2005. Scientists collected the stem cells of Snuppy, aged five, for inseminating other females. The team recently reported that 94 embryos were implanted, which led to four successful births, of which three have been living for past seven years.
