I hope it works. It's based on positive reinforcement so that is a very good thing. As for the rest of it, I haven't tried this specific task so I really have no idea. It certainly sounds well-reasoned and straightforward.

Clicker training is kinda one of those love or hate things - nobody's really neutral on it for some reason. :) I think the stuff he's suggested will work better for this problem. (But I can still get a dog to sit and lie down in ten minutes with a clicker and a box of cheezits.) :)
