Someone already gave example of APHIS / customs dogs. It's been working for quite some time for them and know-how is there.
And you don't need to screen everyone with a dog. Just walk them along the lines at a steadily pace, those buggers love this kind of a thing when they have to find "the thing" to get a treat! If dog alerts, then call over a LEO (or better make TSA into a professional LEO agency) and check the pax from 10 different angles. You can then use WBI, etc. Reasonable suspicion first, molesting later.
Plus, like a mantra: use common sense. Use common sense. Use common sense.
