As the dog grows, you should teach him to walk to enable progress rather than dragging it behind him as he pulls away before. With a small dog that is the worst scenario that may have wrapped the line over and over again, as your dog runs around you, but if you are one of the larger breeds, if not corrected soon, could end up with a real problem.
The unfortunate consequence of the lack of online training is necessary that your dog will miss the simple pleasure of a walk with you. If each walk is nothing but a constant battle, certainly not take no joy, you or your dog.
