I remembered doing this today and finally uploaded it. We recorded it last summer. This is the first time Connor ever saw this exercise, and he is not tied down in any way, nor is he wearing an e-collar. The only thing keeping him in the down is his own self control, and he HATES the distraction. The only thing I am asking him to do is stay in his down and ignore the decoy, who is, to put it mildly, annoying him. Thanks to Chris Fraize for the idea.
