Scientists at Seoul National University, led by the embryonic stem cell research scientist Hwang Woo-suk has produced the worlds first cloned dog, Snuppy.
The puppy, an Afghan hound, was made from a cell taken from the ear of a three-year-old male Afghan hound and the cell was then fused with the egg cell of a female dog, whose DNA had been removed. The female dog acted as a host for the embryo.
Researchers have since cloned cats, goats, cows, mice, pigs, rabbits, horses, deer, mules and gaur, a large wild ox of Southeast Asia. So far, efforts to clone a monkey or another primate with the same techniques have failed.
Snuppy joins lots of other cloned animals including Dolly the sheep, CC the cat and Ralph the rat.
The cloned puppy was the lone success from more than 100 dogs implanted with more than 1,000 cloned embryos.
Scientists hope to use dog clones to help understand and cure some dog diseases - research which, they hope will help cure human diseases too.
Scientists had doubts about Snuppy’s authenticity after it became clear Hwang’s team falsified research claiming to have cloned a human embryo and patient-specific embryonic stem cells.

Hwang Found Guilty of Fraud; Snuppy is Real Cloned DogJanuary 11th, 2006 As reported before Dr. Hwang was able to successfully clone Snuppy, a fact confirmed by the findings of investigative panel at the Seoul National University.
SKorean Cloning Scientist Never Cultivated Patient-Specific Stem CellsNovember 14th, 2006 Disgraced South Korean scientist Hwang Woo-suk, who falsified stem cell research data, testified Tuesday that his team had never succeeded in cultivating stem cells matched to patients. Hwang Woo-suk, who once claimed to have produced the first cloned human embryonic stem cells, said he "succeeded in making blastocysts for tailored stem cells but there wasn't any success in cultivating (patient-specific) stem cells," his lawyer Jung Keun-hwa said after a trial hearing in Seoul.

Cloning Can Help Pet Lovers To Get Their Pet Back May 24th, 2008 Hwang's Sooam Biotech Research Foundation in South Korea and Bio Arts International (animal and human genomic industry) are going to start a dog breeding business in partnership. Bio Arts announced that they are going to start an auction from June 18th, where dog owners can bid a minimum of $100,000 for the right to have their dogs cloned.
South korea to resume cloned human stem cell research once againApril 29th, 2009 The presidential advisory committee after hesitating twice, finally declared on wednesday that South Korea have decided to lift the three years old ban on cloned human stem cell research. The National Bioethics Committee, a presidential advisory group, said Wednesday it has decided to allow a Seoul based hospital, Cha Medical Center to conduct work on human stem cells created from cloned human embryos.
