lol, Mickey does that all the time. Once we were in the basement and he smelled something from the top floor. He went up two flights of stairs, just smelling the air.

My friends' dog has this thing where he HAS to smell at every tree and he stays there for a good minute or so. It's a dog thing, I wouldn't worry. Just make sure you dog doesn't get any more of that bunny poop!
