The world’s first purpose-cloned dogs have started training for their future careers. South Korea’s customs service ordered clones of its very best sniffer dog last year. It hopes the cloned dogs will become experts at finding explosives and drugs at its airports. The cloning will reduce the costs involved in the months of training normal dogs. Only thirty per cent of canines selected for training actually make the grade and become a sniffer dog.

The seven cloned puppies, all named Toppy (short for Tomorrow’s Puppy), were born in October and November 2007. Cells were taken from their Labrador retriever father, called Chase, to clone them. Project manager Lim Jae-Yong believes the clones will be easier to train than ordinary dogs, because of their genes from expert sniffer Chase.

The $300,000 project was carried out by Lee Byung-Chun, who cloned the world’s first dog from a three-year-old Afghan hound. Each Toppy cost $60,000, which is half the cost of training a normal sniffer dog. All seven Toppies have been in training since they were born. They have successfully passed their first round of sniffer-dog tests, although one had to drop out with a bad leg. The dogs train together and all come running when their name is called. Their trainers only know who’s who via a microchip in each puppy’s ear. Lead trainer Kim Nak-seung said: "The differences between them are so small that I really can't tell the puppies apart." The Toppies should complete their training by early 2009 and start work sniffing baggage in the nation’s airports soon after.
