Breathing into a Cheerios box to annoy my dogs

It's possible that the box has nothing to do with it, and it's just the sound of heavy breathing that makes Sven woof.

I discovered this when someone had left out an empty cookie box, but put the plastic bag of cookies from inside the box back into the cupboard. I didn't know it was in the cupboard, so I decided to start hyperventilating into the box until I found the cookies, but it made my dogs woof instead.
