How come dogs have better sense of smell than us?

How do dogs smell things we can't? asks Olivia Minogue, a student in Sayville.
Sniff sniff sniff.
You can actually see a dog's nose hard at work, picking up a scent wafting through the air, following the invisible trail a rabbit left in the yard, or investigating your pants leg for evidence of a secret meeting with a cat.
No one knows for sure how much more scent-sensitive dogs are than humans: a thousand times? Ten thousand?
But what is known is that a dog's nose has many more odor receptors, and an olfactory (smell) center that takes up much more room in the brain.
