South Korean Scientists Clone Drug-Sniffing Dog
RENEE MONTAGNE, host:
Okay, if you ever wished you had a clone to do part of your work, then this is your moment to be envious of a dog. The dog is a Labrador Retriever named Chase. It's a working dog - South Korea's top drug sniffer. And it may soon be able to do much more work, because Chase now has seven genetically identical twins.
