Yes, having a"pack" creates it's own set of problems but the benefits faroutweigh the problems imo. Use the bad habits as a way to train good ones. When they barks say "speak" and then gradually when they bark you can stop them by saying "no speak" or "shhhh". It is really a good thing that they bark to alert you but they shoudl stop when you ask them to. It just takes trainign and repetition and persistence but it is possible.
