While I'm sure someone will come along with more knowledgable advice, I wanted to let you know that Dudley is a real talker as well. He has now started going out the door and immediately barking, even if nothing is there. He also happy barks at people, more of a whiny, come see me bark.
And, my favorite bark is his, "boof" bark--a low bark that is kind of just pushed out the side of his mouth. This is normally what he does if he is getting a little excited and I tell him to lay down. He also clings to me, waking up to follow me around. Just wanted to let you know that you are not alone in this one
