You do have a point. My fear is that my dog would run out of the electronic fence despite the shock just to get the reward on the other side. Our goal is to save up money and fence a small part of our acerage so our dog can have some play time outside. Thats the plan. I think it is so great that you took the initiative to stop and rescue that poor dog. You are a good soul! Most people would have went on and not thought twice about it.
