You should take some strategies or skills to educate your dog. This doesn’t mean to hit hard at it. A Also, hitting cannot make your dog obedient.
If it is wrong, you must punish it, but choose the same way each time. Hit its right face with your left hand; it will therefore feel ashamed for its behavior. Then it will criticize itself and become honest. Maybe it will feel depressed,but you can’t comfort it immediately, otherwise all your previous efforts will waste. You’d better stroke it with your right hand after it reflects on itself for at least half an hour.
Why do you need to distinguish between the two hands?
If you use the same hand to hit and stroke it, it is unable to distinguish between the penalty and comfort. But if you differentiate the meanings of two hands, it will know it has made a mistake when you lift your left hand, and when you lift the right hand, it will immediately understand that you want to stroke it. Therefore, it will get close to you to wait for your caress.
