Give him about two weeks to get it down - it usually takes many repetitions for dogs to understand they can't pull as they get so excited and amped by all the sights, gillions of scents and all of the energy of being outside on walks - kind of like we are when we step off the ship in a new country and start a vacation. Excitement is thrilling them with the whole of the outside and it does take a while to imprint their brains that that excitement and enjoyment is okay as long as they don't pull or go wild when other dogs appear on the same sidewalk, etc. You are doing great so keep it up and stay patient as he learns what you are teaching him. Yorkies are terrifically smart and eager to learn once they understand they can't get away with everything they keep trying over and over at first. Eventually, if you stay on course with patient, loving and gentle training with positive reinforcement, they get the message that you are bigger, just as determined as they are and that they are best served and get better results by not pulling ahead but walking alongside you and keeping you pleased and happy with them rather than displeased or unhappy.
