I'll let my ( now six months old ) Jack Russell out of the crate, got out for his morning business, play, plenty of petting and rubbing, and with some coaching. I have the choice to have him to go to my in-laws for the day. They own 2 dogs, a Golden Lab ( two years ), and a Jack Russell ( seven months ). It springs from folks who are not totally competent in working with dogs. That is the reason why it works so well with dolphins : Because they are stuck in a tiny pool when they are not being trained. But using it to the dismissal of all of the other tools to hand and you are being blind.
