How about start training a bunch of bomb-sniffing dogs?

Expensive and rare things, trained dogs. They aren't stamped out in Chevrolet trunklid factories.

True enough. Cost for a trained dog starts at about $20k. And they have to be trained just about every day by an expert handler for at least an hour or they revert to a very expensive pet.
