We had work done in our basement to prevent flooding. That meant that we had almost an entire day with jackhammers going in the basement. It caused the floor of the upstairs to vibrate pretty noticeably.
For future reference, dogs do not like this. However, it resulted in the cutest picture yet of June and Larry:
Two unhappy doggies curling up together for comfort, on a foam footstool that protected them from the evil, shaking floor (that mommy and daddy were doing nothing about).
