The next step, once you and your dog have mastered "Backwards is the Way Forward".
Walking backwards with the dog steadily bringing the sheep up to you at the pace you choose to move back at, is one of the best exercises you can practice with a trainee dog. It will improve the dog's stop, its control of sheep, its working pace and the distance that the dog works from the sheep. In this tutorial, we go a stage further and turn our back on the dog.
Once you can trust the dog to bring the sheep steadily up behind you as you walk forwards, your training will have moved onto a new level.
