I have some ideas on how I'd do it based on my recollection of some prior readings.
My thought would be to have someone drop some hot dog in my back yard. I would walk my dog on a leash and prong and command him to leave it. We would walk by it an additional number of times...if he paid any interest in it he would be corrected on the prong.
Or, should I be using the ecollar instead of the prong hear? My thought would be to use the trusty old prong for which my dog understands that any prong corrections come from me. As my dog has never before had an ecollar he may not associate an ecollar correction with me, at least not in the beginning, which leads me to the next step.
I would put the ecollar on my dog and release him into my back yard. I would discreetly watch him, hidden behind a window in my house. I'm guessing he would approach the hot dog cautiously to investigate further. And when he got to within a few feet I would zap
the crapola out of him!
And then I would repeat this process both in my yard and out and using different foods until there was no doubt that there is no way he would eat any food on the ground anywhere.
Ok, stop laughing and calling me stupid and tell me what's wrong with this and the better approach.
