Positive training works! We have sold to trainers that train this way. In our experience, and we are not trainers...positive training in every area of life including the human world in sports and with dog training motivates us and our puppies to do our and their best. We observe that the natural dog world does however include no. Mother dogs tell their puppies no. Dogs tell each other no. They are hard wired to remember no’s. So when we train dogs, we use a few no’s. We encourage you to find the balance in your training.
