Thanks guys!!
He actually likes wearing that little gray shirt because it keeps him warm (he is more than willing to put it on when it comes out) and the silver bells around his neck are to keep me and others from stepping on him, since he tends to stay underfoot and I've never had a small dog before, so I'm not used to looking out for one.
He's already spoiled rotten because he's such a little sweetheart. Even though he was the largest pup in the litter he's the most mellow, and he's so smart and willing to please.
He knows (so far) how to sit, sit up, stand, shake, and lay down. I can't wait until he starts obedience classes. He's gonna be a star student!
