For the next and final method of teaching your dog to walk well on a loose leash, we're going to use a variation on the "Start/Stop" method outlined in my very first blog on the subject http://www.alldogstoronto.com/the-all-dogs-blog/leash-work-part-one-how-to-walk-without-pulling.
Protocol #3: Go Together
Continue to walk your dog while the leash is nice and slack. Stop whenever it goes taut. If your dog stops at the end of the leash and waits for you to catch up, turning her head to look your way, be sure to give her a big reward. Immediately start walking again.
The next time your dog stops and waits for you to catch up, the moment she is by your side, be sure to immediately praise and treat her for a job well done. This is exactly the positioning you want. Your dog will learn that by staying close to your side she will get not only extended walks, but also a tasty food treat. That's about as straightforward as it gets!
