and Biotechnology at Seoul National University, which cloned Snuppy, was led by Woo Suk Hwang. Snuppy has since been used in the first known successful breeding between cloned canines after his sperm was used to artificially inseminate two cloned females, which resulted in the birth of 10 puppies in 2008. In 2017, 4 clones of Snuppy were made by Sooam, and were the first clones made of a cloned dog, to investigate potential health effects of cloning.
