completely disagree, why would you do anythig where there is a chance to hurt the dog,ther is much simpler techniques,
personally I would use a slip lead, ensure it is on the correct way, raise the lead right up to behind the dogs ears, and walk with the dog on my left hand side, walk round in small circles or a figure of eight in a wide open space, praise the dog when walking correctly, should soon cotton on and then gradually make the excercise more difficult.
with the running away, you should really enforce the recall, you need to be of greater importance and more exciting then the
