So I want to talk a little about punishment-based training - what it is, possible repercussions of using it, why it's so popular, why it's unnecessary, and why I know what I know about it.
First, what is it? This is any training that emphasizes the addition of an unpleasant stimulus to cause a behavior to be less likely to occur in the future. In other words: doing something to the dog so the dog stops doing a behavior. This can be anything from yelling " no," to poking the dog in the side, to using a prong collar, to hitting the dog. Let me emphasize something here - IT DOES NOT HAVE TO BE ABUSE TO BE PUNISHMENT. You can punish an animal without being abusive, at least within the scientific definition of punishment.
