Not that I'm any dog training expert, but this sounded promising:
Dog Obedience Training. Point being, though, it took all of one, lousy minute to find a possible solution for humane training methods for dogs. I'm told over and over again by my shelter friend that mostly what it takes is education of the
guardian, kind training methods and commitment....the latter being the one most often missing in people. So yes, I'm SURE there are always better ways.
