While most owners aren't sadistic towards their dog, their ignorant actions when it comes to collar introduction and use are just that. I've heard, seen and actually been a part of that ignorance. Instead of "collar conditioning," or teaching the dog what's expected of it and how to get out of an electrical correction, too many people strap the collar on and start zapping the dog. To the dog, this electrical shock is akin to the "Hand of God" coming out of nowhere and lighting up his life.The dog that is shocked and has no clue as to why it was, how to turn it off or avoid it altogether will become confused, scared or both. They'll often times do one of two things: either shut down and refuse to do anything or they'll head for the hills in an attempt to get away from the mysterious, sudden and unpleasant (and often painful if set too high) experience.
