I haven't seen that dvd but when I first started training 2o2o I did use the command "touch". I've also heard "Easy" and "bottom" and "toes" and "paws". I try not to use any command anymore. When I tell my dog to "walk-it" to do the dogwalk, I expect him to go to the end and stop in the position. It is the same mentality that I don't say "weave weave weave weave weave weave". When I tell my dog to weave I expect him to finish all the poles without me having to tell him each one. This probably wouldn't work while training but it is something you might consider in the future. This works really well for my dog in class and practice but at a trial we have issues with this method so sometimes I still say "touch" at a trial.
