 Veterinary professor Byeong Chun Lee took over leadership of the team behind Snuppy . In 2008 , Snuppy became involved in the first known successful breeding between cloned canines , after sperm taken from Snuppy was used to artificially inseminate two cloned females , which resulted in the birth of 10 puppies . Nine of the puppies survived . The SNU team , under Lee , have gone on to successfully clone over 30 dogs and five wolves . After successfully breeding the cloned wolves , Lee claimed that the ability to breed cloned canines makes it possible for working dogs which are usually sterilised before training , such as sniffer dogs and guide dogs , to reproduce . SNU , which claimed to own the patent for the process used to clone Snuppy , formed a license agreement with RNL Bio , a commercial pet cloning company . Hwang entered into a partnership with RNL Bio 's competitor , BioArts International , which caused an ongoing legal battle into who owns the patent rights although Bio Arts withdrew from dog cloning in 2009 . RNL completed the first commercial cloning in August 2008 but ran into financial trouble in 2013 .
