Getting healthy, well behaved dogs is what people want when they get a puppy. That is the reason why we use Early Neurological Stimulation on our goldendoodle puppies. This method puts them in unique and unnatural situations so later in life , they are calm and more flexible. Even though goldendoodles are usually really mellow, calm, easy going dogs, I can see the difference.. We start Early Neurological Stimulations when our puppies are 3 days old. Our experience is, that they are a lot quiter, calmer then previous litters when we didn't use it. Most likely they won't be so scared of those loud thunderstorms and they will be less stressed in different situations.
