There is a story (you'll have to register to see it) in today's New York Times about dogs being trained to sniff out all kinds of stuff, not just bombs and drugs, but bedbugs, DVDs, and mold. Most dogs in this line of work are ones rescued from shelters. As long as they enjoy the work and aren't put into dangerous situations or made to sniff harmful substances, then I'm glad these dogs are being rescued.
