I saw an episode of 'me or the dog' with Victoria Stilwell with an excessive barker. She gave the no bark command (she used quiet and hand signals) and then gave the dog a small piece of chicken. After the dog figured it out, he was better.
Not sure about the second or third. How long have you had him? I adopted a 3yo female last week. She was doing the same thing but now has it figured out. I have another dog and I think that helped.
