security

I always joke that louie is "first line of defense".  when we were in the big house (not prison, just nearly 3x the size we're in now), we had a dog door and when I'd go to bed, if louie heard something he'd go investigate and ella would stay on the bed.  I figured they'd decided this early on in their security plan, so that if something happened to louie and the intruder got by him, ella was there to scare him to pieces.  she's so quiet (except for the snoring).  it's probably more like she's lazy, but I like to give her credit!
