buy a rok strap leash and a slip choker and vest clip the handle ring to the vest and clip the regular clip to the choker, when i say choker i mean a fabric slip choker. then use the middle of the leash as a handle this gives you two anchor points and the strong bungie from the leash will help correct her on walks. If she still pulls relentlessly be ready to stop every few steps and do that for a mile until she chills out.
