Dog noses are 10,000x more powerful than a human’s. But they have 80% fewer taste buds. A dog’s brain craves scent.

• Scent processing through a dog’s nasal passage is detected by 220 million scent receptors.
• In a dog’s brain the olfactory bulb is three times the size of a human’s.
• Dog noses are stereoscopic, with one nostril identifying a smell, and one locating it.
