We trained our Irish Setter using a shock collar as a training aid, it is a really nice one with an adjustment for the level of shock on the remote. It was only turned up as high as we needed to get his attention; our setter would get so focused on hunting that he "forgot to listen" when we tried to call him or give him a command. We would give him a tickle to break his focus and he would check on us for orders. lol We got to the point where he got all excited when we pulled the collar out of the closet.
