Since about the time of Angus' surgery (Jan 2006), he has been doing what we call "the old man cough." It's a dry hack sort of cough. In the past three months, it has change to be much more intense to include a loud vocalization. It's like "he's trying to throw up a human being."
We took him to get checked out and were given Lycopodium. We don't remember the strength. We gave that to him yesterday. So far, no changes.
