My nose is more powerful than my bite

My name is Bruin.

Of all of the weapons I have, the most powerful is my sense of smell. I can follow a scent people can’t detect, even a scent trail that’s up to 12 hours old.

One of the reasons is my nose is much longer than yours. The inside of your nose has an area of about one inch. My nose has an area of almost 36 inches, or one yard. So there’s room for 220 million receptor cells inside my nose. Your nose only has 5 million receptor cells. That’s why I can smell drugs wrapped in plastic, hidden inside coffee grounds.

I can be trained to use my nose to search for suspects, victims, drugs, or explosives. When I’m working, I sniff six times per second.
