The clones are being trained near Incheon International Airport, and all are reported to be healthy. And, strangely, they've all been given the same name: Toppy. Each one cost between $100,000 and $150,000 to clone, but that investment could pay off in the long run, if they become successful drug detectors. The dogs are now part of the way through a series of tests set up to establish whether or not they're really fit for the job. Good genes aren't always enough, after all.
