Query: complete training pattern but coercion based training

When then book originally came out it was quite forward thinking in its methodology. Fortunately for our dogs there has been a quiet revolution in dog training to a less coercive method of training. For example, her method of teaching sit involves pulling up on the collar while pushing on the dog. In short physical discomfort is being created for a command that the dog does not even know. Her methods are based on negative reinforcement. The correct response will make the discomfort vanish. This type of training can be effective if you have the right dog for the stress it will produce and if you the handler have great timing and can always perfectly and rapidly make all pressure vanish when the performance is correct.
