Man's Best Friend Forever: Cloning Dogs for Love and Profit (Column‪)‬

"ARE THEY all related?" a woman asks as she watches three puppies romp around Eastwood Park, a little slice of doggy heaven in Mill Valley, California. One of the pups, Mira, is notably larger than the other two, Chingu and Sarang, but they all share similar markings: white snouts and chests, darker fur on their backs and crowns. "They're clones," Lou Hawthorne replies. The woman smiles as if Hawthorne's joking, but he's telling the truth; all three puppies were created at a commercial animal laboratory in Korea using tissue collected in the late 1990s from Missy, a beloved mixed breed that belonged to Hawthorne's mother and died in 2002.
