My horse was already used to electric fences and had me laughing so hard I could barely stand. We put 6" T post stand offs on after rebuilding the fence. Darn horse decided that he just had to chew on them. He would carefully maneuver his nose to avoid the fence so he could grab the stand off. Just as soon as he bit down he would hit the fence and get shocked. He then would jump, run, buck, stomp and obviously be pissed off about being shocked then go back and do it again. Tried half dozen times before giving up on the chewing.
