So for dogs, the air coming in through their nose goes to two separate places, their lungs and the spongy area in the back of their snout, which means that the scents are getting collected and concentrated instead of getting diluted from the air.

And then the other part of the dog nose anatomy that helps them smell better are these little slits that you've probably seen on the sides of their noses. That's where the exhales go. And when that happens, it creates this little vacuum that sucks more air into their nose, which means they can smell more with that second or third sniff.

What a delicious life, the life of a dog. Right. And Lauren says one of the reasons dogs are able to distinguish these low amounts of an odor in these complicated environments is because dogs have a lot more receptors for different what we call odorants, which are molecules or chemicals in the air that make up an odor, basically.

And different odorants can activate multiple receptors in the dog's nose. And that translates to a kind of specific code for the dog.

They're basically chemists. Yeah. But this is actually a part of what Lauren studies, trying to understand what exactly it is that a dog is smelling.

Oh, from like a chemical standpoint. That's interesting because thinking about Colette's work, If you want Jack to smell whale poop, don't you just need to kind of show him the whale poop? Why do you need to know on a chemical level what's in a different target?
