Thanks for all of the quick responses! I'm glad this is such an active community.
I need to talk to the breeder about DNA testing and other health issues, because I don't think this dog is/has a pedigree. We live on a tiny, itty bitty island called St. Thomas where dog breeding is not popular at all; it's a miracle we found a full-breed anything - this is our first non-random breed dog. There aren't any training classes I've heard of, either, but we do have two dogs in neighboring houses which the puppy will be visiting often. We do have good vets here, and will be taking the puppy to ours within a week or two of having him home. Thanks for the helpful sites, tanza!
Pictures will be up asap, I promise! Chris got a new camera for Christmas, and you know how people with new cameras are, let alone people with new cameras AND new puppies!
Thank you agile for the toy recommendations! We're picking up the pup tomorrow (wheeeeee! :D) and buying these things today and tomorrow morning, so I don't think we have time to send a toy or peice of clothing. I'm hoping since he's so young, we'll be able to make him feel like we're his family, and he'll want to protect us and our home while we're here or away. I know they can't bark, but I have read that they have an aversion to strangers, which is what I'm hoping will at least lead to some menacing growling should someone manage to enter our apartment while we're away.
Finalizing doggie-proofing in the place right now; thanks again all for the suggestions!
