This really is a hard nut to crack, but some dogs do learn the *no bark* command. I would get a couple good dog training books from the library and look up the techniques which are recommended. If all else fails, you could get one of those collars which allows a free bark and then gives off a warning and a mild correction. One of our friends uses it for his little dog who we sometimes care for when they are on vacation. Rita doesn't mind wearing the collar and it really does work. I don't like the idea of it because it has these two prong things that seem to poke into the front of the neck, but like I said, Rita doesn't seem to mind it.
