When getting a scent, why do dogs do a bunch of short, little sniffs instead of one big one?

I would imagine you would take the scent in a lot better on one big inhale through the nose.

No with scent you need lots of movement of the particles over the nasal cavity for the receptors to catch them.  Short sniffs do that.  A long breath doesn’t as much — and if what you’re smelling ends up being bad, you just breathed the bad thing all the way to the bottom of your lungs.
