The dog is not able to blame the cat for this one.

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.

Normally.

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.
