When my dogs sniff at a tree or dirt patch with special enthusiasm, I wonder what kind of information they’re getting. Their amazing noses allow them to “see” a world that’s practically foreign to us humans.
Over the years, smart people have found ways to harness that nose power to help detect drugs, cancer and illegal DVDs. Now they’re training Cocker Spaniels to sniff out cash-carrying criminals and Poodles to detect peanuts to help kids with life-threatening allergic reactions.
When you take your dog for a walk, is it more like going for a sniff? Does s/he put her nose to the ground or prefer air scenting? What's the strangest thing your dog's nose has discovered?
