Mystery of the Exploding Dog

The plot thickens. I seem to have found a clue to Ellie's gastronomic explosiveness last night. When we came downstairs this morning, there was a perfectly clean butter wrapper on the dining room floor.

As far as I can tell, this is the same butter wrapper that previously contained half a stick of butter subsequent to my popping corn last night. What I can't explain is how it got into doofus' hands... paws, actually.

The butter never left the kitchen counter - I have no idea how Ellie could have gotten into it. But it's no longer on the counter, and I have a licked-clean wrapper where there once was none. It seems pretty obvious that in some mysterious way, my pooch got her mitts on a good hunk of butter right around bedtime, scarfed it down, and was almost immediately sorry for it when her stomach began growling. By the time I would discover the remains of her feast, it would all be over, with nothing but the stench lingering in the air.

Has my dog learned the secrets of levitation?
