Wow, what a lot of good tips you've been given. It may seem amazing but I think I might have a new one that hasn't been mentionned yet. The
Ultrasonic Bark Stopper. I've never used it but have heard it might work in cases like yours where you have the problem of your dog bothering the neighbours. Not as a substitute for any other training ideas but you can't have your pooch barking for hours, which might lead to serious complaints and demands for her removal.
