You don't think those same things traumatize the dog too? There's a reason why all reputable dog trainers advocate exclusively positive training methods. It's because training with exclusively positive feedback is not only most likely to get the behavior you want. It critically avoids destabilizing the dog. Negative reinforcement learning does works, but it also leads to anxiety, and "reactionary outbursts". i.e. the dog learns to become afraid, and is more likely to bite you. Only abused dogs bite their pack in fear. Just like only abused humans attack their community.
