Humans are actually ridiculously good at smelling petrichor, that earthy smell before it rains. We're better at detecting that smell than sharks are at detecting blood in water. Why, I have no idea.

Yep, a dog can pick up a scent from up to 12 (yes twelve!) miles away.

Wouldn't the concentration matter way more than the distance?

I can also smell a forest fire 12 miles away..

Dogs can smell the time of a scent. Way more brain involved there. We can just identify more smells.

Dogs have around 300 million scent receptors, which is why they have such an acute sense of smell. We smell more scents, but less acutely.

They have far more scent receptors and larger parts of their brains dedicated to their use.
