Without discipline a puppy will turn into an unmanageable dog that no one wants to be around. We’ve all seen them, the people in the park yelling at their dog and being hopelessly ignored, that’s not what you want to be like. If you want to keep training to a minimum then sit, stay and come will help you and your dog cope in most situations. Being consistent is probably the best of advice you can get when it comes to the nitty gritty of dog training. More dog stay command advice and information.
