He likes to sleep with his head under things. Mostly cushions, but also the easy chair and the couch. And sometimes he lies on his back and hides his face with his front paws, but I don't have a good picture of that yet, damn it.
I still can't get a good pic when he's not sleeping. He doesn't like sitting still! At least you can really get an idea of how freakishly long he is that second pic.
He was much better today! He clearly did a lot of ripping around my bedroom, but he didn't damage anything (well, that's not true, he put a small scratch in my crappy Ikea nighttable, but it seemed like nothing after yesterday!).
Thanks again for all the help and advice. I'm having so much fun with my new puppy!
