If you pay attention only to 'bad' behaviours - even with hitting, yelling, and so on, those are the behaviours the dog will continue to do. If you ignore them and acknowledge the 'good' behaviours, you are likely to see the dog display more of the 'good' behaviours. The dog is choosing to do the 'right' behaviour because he wants to and enjoys doing so. Dogs desire human attention. If you aren't ignoring your dog for 'bad' behaviour, then you're reinforcing it.  If you pay attention to both 'good' and bad' behaviours, then you're confusing the heck out of your dog! Because both are being reinforced, the dog will continue to do both. If you do physically or verbally punish the dog, you run a very high risk of creating much worse behaviours than the ones you started with. Punish your dog for 'bad' behaviours and you risk creating aggression, fear, anxiety, learned helplessness, or a stubborn dog. Sure, you may immediately suppress the 'bad' behaviour, but that doesn't mean that the 'bad' behaviour is gone forever. For example, punishing your dog for jumping might make him become so afraid of people that he bites instead of jumping. You may sometimes hear the phrase 'balanced training'. What this means is that the trainer uses traditional, force-based techniques, as well as positive reinforcement when the dog is correct. As discussed previously, this is just confusing to the dog and makes him less likely to offer behaviours. This type of training teaches the dog to possibly work for you to avoid punishment, but it does not teach the dog to willingly work for you. Other dogs may just shut down from the punishment and end up doing absolutely nothing.  It's more effective to teach dogs' minds rather than manipulate their bodies. Then you are working with, rather than against, your dog during training sessions. It is more effective and kinder to help inexperienced untrained dogs rather than reprimand them. Positively trained dogs - those who are not punished - will freely offer behaviours in an effort to elicit a good response from their trainers, will grasp information more quickly, and will be able to learn more advanced behaviours at a much earlier age than most other training methods encourage.
