Honestly-I'm getting anxious just reading your post-I'm sure this little one is feeling the same way. Sounds like you really want your new puppy to warm up to you and his surroundings (which is good) but take it slow. His whole world has literally changed.
Has he been to the vet yet? Maybe take him for a check up to make sure he's feeling ok.
