I bought a 5 month old poodle who had never been on a walk, let alone a leash either. She was extremely reluctant to walk on a leash, but my husband and I figured out a system. He would hold the leash and I would walk in front with a treat. Each time I walked a few steps in front, and crouched down to her level facing her and ask her to 'Come, Mochi!' in a very upbeat voice. The exercise taught her the 'come' command and taught her how to walk on a leash at the same time. Each time you repeat, increase the number of steps between you and the dog and pretty soon they are well on their way to being leash trained! All in all, it took probably a full afternoon of doing this and she hasn't had any problems since.
