Your dog is so cute! And yes training is very important for the dog but more important for the "owner" to learn to understand the communication of the dog. and yet there are so many "dogtrainers" in the world who have no clue about dogs. A dog never needs punishment if he's doing something wrong. He's doing it wrong because he wasn't tought to do it right. A dog really needs the chance to understand fully what we want from him. And if dogschools are working with punishment the only thing the dog is learning that he cannot trust you. ...i hope you have a good school that works with positive reinforcement :) ...i will follow you to see more of your story with this beautiful girl.
