All of this dog training had to start somewhere. The difference between Blanche Saunders methods and Bill Koehler’s methods were, Bill Koehler advocated associating an undesirable behavior with an unpleasant response, Blanche Saunders associating a desired act with something pleasurable. She did advocate negative punishment for some behavior problems. She said “They must be disciplined when they do wrong, but rewarded when they do right”. Even so, we still don’t want to see negative reinforcement and punishment today. These are old outdated methods.
