It's a electric fence. I know about being kind to dogs. It's better then him getting scoldings all the time or me just letting him go. Most dogs at that age would of gotten the hint by now. He would get in trouble and be in there an hour later with my plants tore up again. In a way this is better. It's up to him. Touch or try to jump the fence he gets stung. Not me coming home and seeing devastation and scolding him. Im out of back up plants and this couldn't go on. He'll only tempt the fence a couple of times if he hasn't gotten it by now. Between the fence cost, Vet bills for a foxtail in his throat and neutered and shots, I have to much invested to turn him lose. He was brought home for the same reason of the things he is destroying.
