Dogs tend to naturally follow a confident, relaxed, calm person. This is why Cesar can usually get most dogs to respond to him without trying. It is just his natural demeaner. Any training method/thought would work for him because he is 90% there by not being anxious of afraid of the dog, or afraid of doing the wrong thing. I am not a Cesar fan. But that just seems to be true of him.
Some of us have to work a little harder at it, and age, experience, both improve our leadership skills over time. We often have a much easier time with dog number two, because dog number 1 trained us, and we are not as worried about being the perfect pet parent, with the perfect puppy. That frees us up to be able to help each dog's individual requirements, when we aren't stumbling over our own impediments.
Relax, you will make mistakes, and the dog will not be perfect. But if you are relaxed, it will make the mistakes you make less onerous, and the imperfections in the dog less serious.
In fact, I believe that the long-term effects on our pup's from outside stimulus is 95% our response to the reaction/situation. If we remain calm, and do a "shake it off" type reaction, where we remain in control, the pup will soon be romping and playing like nothing even happened. If we rush to the puppy and pick it up, and hold it, and make a to-do over it, it is likely to imprint a more lasting response. If we are angry and start shouting at another person, that is going to imprint a more lasting response in the dog. Don't panic, don't get angry. Maybe what would be best is a prescription for valium for new puppy owners. Just stay calm.
Even if the pup is a bloody mess of broken bones, or ate a bottle of IB profin, panicking is not going to help you or the pup. Remain calm and act appropriately for the situation.
Good leaders form bonds with puppies, and training is a great way to solidify the type of leader you are.
Praise the dog. If it does something wrong, help it do it right and then praise. Temper praise for the situation and how well the action is performed.
Do not repeat commands. That encourages the dog to ignore you.
Do not give commands that you cannot or will not follow through with. If the dog is halfway across the yard going after a squirrel, don't tell him to COME! The dog will learn that he can listen to you when he wants to. Teach him first, and get it solid and then give him more reign. Then make sure he is solid before expecting him to do it off lead. Practice that, and learn your dog. Even if he is good at complying off lead, don't give the command if there is a serious distraction if you think he may not comply.
Instead of trying to make the dog what you envision him to be. Learn who your dog is, and tweak that into the dog that works well in your life. I mean, if you want a top level obedience dog, and your dog is a crazy happy goofy flyball type dog, then maybe you can work with him in agility or flyball or free style or frisbee. Don't try to press a square dog into a round hole. Help your dog reach his potential by learning his strengths and building on them. The weaknesses will improve as the dog's confidence and desire to work with you increases.
