I do not have a subscription to this, but from what is shown, one could get an idea of where to keep their dog treats!
Oh, sure. How long before someone gets bit in the boob by an enthusiastic dog? Right up there with spitting treats at your dog to get him to look at you. (some "trainers" actually advocate this!!! But only the ones who don't understand how to train such a simple behaviour). I think if I needed to keep treats handy I could find a better location, although granted some clothing doesn't have pockets.
