Each dog is an individual, methods that work for one may not work for another. Generally speaking though, each given popular training method will work for most dogs. I'm pretty gentle with my Tosas, because they're very sensitive to me. For training off leash though, i've used an electric collar sparingly to correct bad behaviour. Such as taking off to visit the neighbours and not coming back to me when called. :( You may want to find a training club or a good private trainer and they can help you figure out how to motivate her.
