I have used stick fetch with all my dogs. It is another form of pressure that they are introduced to that
I may, and have, use in the future. As far as whacking them I don't think I would use that adjective.
I have a helper behind me and we go down the line with alternating: fetch only, light tap, fetch only , little harder tap, and
I can honestly say just a fair tap to introduce the heeling stick and have had good success with it. Just spend a day or two and
have been glad to have this tool in my tool box. I will add that I am particular with what task I use the stick with. I actually use it to help
me work on heeling forward and backward. I do not like to use it on line for sit as I feel it can make the dog too crunchy and worried.
It can be a useful tool if used correctly. I will rub it gently on the dog to get them use to it and to not be afraid.
