How good is a dogs sense of smell? Good enough to smell electricity

<snip>Dogs can smell human fingerprints that are a week old. Their noses are so sensitive that they can even smell electricity. While conducting an experiment, a researcher found that a dog could smell which of two boxes contained an electric current.

He concluded this was because the charge resulted in the release of tiny amounts of ozone that the dog could detect. The source of the dog's exceptional ability to smell is its wet snout.

The moist leathery surface acts like Velcro, catching even the tiniest molecules of smells, then dissolving them so that the dog's internal smell-receptor cells can analyse them properly. To keep its nose wet, a dog must produce a constant supply of mucus through the nasal cavities. Scientists reckon the average dog produces a pint of this mucus every day.

That smell when you plug in new electronics... that's ozone.

Amazing, huh?

I watch mine and try to figure out what they are doing.....
