Our dog is typically very well-behaved. Sure, she gets a little excited when people visit (usually for the first 5 minutes). But pretty much, we trust her to have the run of the house while we're gone. And normally, no problems occur.
Insert Evidence A:
See the blue?
We were at a holiday party. We came home. And there were blue footprints on the floor. SOMEONE had found a pen, exploded it,and trotted in it.
Yes, I realize this means we were lax on the pen-minding. Our fault for leaving that on the floor. And yes, I realize that pens look an awful lot like chewy sticks that you give the dog for treats.
But. That still doesn't make her look any less guilty in the photo.
