While the front part of a dog's nose is almost entirely committed to respiration, the rest is committed to olfaction — the sense of smell — and since there are hundreds of millions more olfactory receptors in a dog's nose compared to a human's nose, a dog is able to smell more and detect a scent in much smaller quantities: «This means two things: A dog definitely experiences smells, odors — volatile molecules — that we don't,» Alexandra Horowitz, assistant professor at Barnard College and author of Inside of a Dog, told Modern Farmer.
