not for all dogs, Danny. I spent several hours over the course of a few weeks with Buster (my avatar image) trying just that, to absolutely no avail. He pulled like a steam train and nothing would deter him. I even resorted to a full-on choke chain - no effect. He just kept on pulling until he nearly choked himself, but it did not stop him. I just had to put up with it. We had him for almost 13 years. We later discovered that all 10 of his siblings had been returned to Dogs Trust within the first year, because they were completely unmanageable. The woman told us that she was surprised we had kept him, based on what the other owners had said about the returned dogs. We also tried professional trainers, who basically agreed that it was a waste of time trying to stop him pulling. One stated that he had never encountered any dog in over 20 years, which could pull as hard as Buster, and was totally unamenable to training.
