I use it because it works, to build an awesome confident stable dog with good manners.
None of my dogs or those I train with are shut down, timid, and worried except those that come from the kind of training you seem to prefer. and those dogs quickly turn around, as did this one.
Sorry, but I prefer to address poor behavior immediately, and clearly so as to set boundaries, and rules the dog understands clearly, and as such become comfortable, safe, and self secure dogs
