How much more powerful is a dog's sense of smell compared to a human's?

A dog's sense of smell is 10,000 to 100,000 times more powerful than a human's. This incredible ability stems from their olfactory bulb being 40 times larger proportionally than ours, and possessing up to 300 million olfactory receptors compared to our mere 6 million. This allows them to detect odors at concentrations far below human perception, essentially smelling in "stereo."
