Here is a video of one of the dogs in a current class of mine. Tess is a fairly typical 13 month old GSD who has learned that pulling on the leash and bouncing around gets her what she wants.

This is her third class with me, and you can see that her owner (the lady in the background, that's me handling Tess for this video) has done a great job at taking what she has learned in class and applying it CONSISTENTLY every single time Tess has a leash on.

Tess might still be attempting to pull, but is remembering herself that coming back is a successful strategy when pulling no longer gets her what she wants. The most I might do is take a step back to remind her (taking her further from what she would like to get to), then as soon as she turns her head back - click!

Tricia (camera person) has her poodle with her, providing an appropriate level of distraction for Tess, no more than she can handle, and not much less either.

Remember - every time your dog gets somewhere on a tight leash a fairy dies and it's all your fault. Think of the fairies.
