Thank you everyone!! hughesjo, I love how they sleep like that! What a cutie pie you have! But really, aren't they all just cutie pies?
I don't know how you could just leave your dog, either

The fact that they did that rather than taking the dog back to the breeder makes me think he's most likely the product of a puppy mill...well, that and the fact that he had parvo and other concurrent infections to begin with. :-/
Anyway, he's healthy now and he arrived early this morning! No pics, because it was 2 am and we were half asleep, but I'll post some soon. So far, so good. He potties outside and has already picked out his "place." I'm not so crazy about the fact that it's a foot from our outdoor dining table, but better there than a foot from the indoor dining table!
Also, he LOVES his crate. He ran to it immediately after we put him down in the house, smelled it, then gathered all his toys and "stored" them in there. Made our night a whole lot easier! We got a light-weight one, so we carried it to the bedroom when it was time to go back to bed and he wiggled on in, rolled around for a bit 'til he got comfortable, then promptly went to sleep. He slept through until the hubby and I got up at 6, and then went potty outside. Fingers crossed that it stays this easy!!!
