"Top" 'Em Up

I've come across some news in the latest Chosun Ilbo that both impressed and disturbed me at the same time. South Korea's Seoul National University has cloned 6 white labrador retrievers to be used as drug-sniffing dogs at the airport. The Korea Customs Service commissioned SNU to create them. Even more disturbing is the fact that they all have the same name! Toppy, short for "Tomorrow's Puppy."

This takes me years back to Korea's first cloned dog Snuppy (SNU + Puppy). I wonder how he's doing now.

Anyway, apparently Chase is the name of the father of the Toppies and he is the best sniffer dog at Incheon International Airport. So instead of training actual dogs to do the job (as Chase must have been at one point) they decided to clone a whole fleet of them!
The next step is to train them to differentiate between different drugs. What I don't understand is that if they are going to have to train them anyway, why not just use regular dogs? Don't all dogs have incredible senses of smell?
What's next? Is it just me or does this spell a frightening pattern of behavior for the future? First animals...
