Maybe a little hyperbolic, but I've seen other studies that show humans can differentiate between odors better than dogs.

Dogs seem to be great at detecting odors in low concentrations. Once they are detectable by humans, however, it seems we have some pretty good olfactory skills.

Smelling is more than just being able to detect an odor. You also need to be able to understand what that odor is. The capacity to recognize an odor from a certain volume of smell chemicals being tipped off is actually a distinguishing pattern of multiple sclerosis!
