So, how does it work…do you say "come" and if she doesn't respond you "beep" her? Clearly, at some point she had to get the shock to have made the connection with the beep. And it had to have been startling enough to have made an impact.
Of course it is your choice. And I can understand your desire to let her run...but, there are other options...like dog parks, or fences, lure coursingor even underground invisible fences are better because the are 100% reliable about when the warning and correction come...humans can never be that reliable.
My dogs run like that every day in their fenced yard....
I am sorry if it sounded like I was attacking you....I have had a hard day
