I just wanted to add one more thing, sorry , some dogs are naturally, genetically, more stubborn than others, and also not so quick to learn. I have to say, our neighbors Shepard is much more quick with learing things, then Dale. Shepards are highly intelligent dogs. But i knew Swissie's weren't *the* most intelligent breed around, and can tend to be stubborn at times. This type of collar has allowed me to get through to him, in a way that works for *his* personality type...just the same as potty training...paper training may work for a 15 lb toy poodle, but would certainly not be an option for a Swissie. We certainly do use treats and so forth when training, from a day to day basis...just in this department, a pronge is a neccessity. OKay, I am done
