We adopted Ollie when he was 6 months old and he is now a year and refuses to walk if you hold the leash. We are moving into our new home in a few weeks but it does not have a fence yet. He will walk around just fine if the leash drags on the ground but lays flat to the ground as soon as you pick it up=! I've tried treats and nothing is working. Any tips? I would love to take him for walks and get this under control before we move.
