We use the Early Neurological Stimulation training method with all of our puppies from day 3 to day 16. The ENS is a training program that was developed by the military to help produce dogs that were healthier, more able to withstand stress and easier to train. The training takes less than a minute per puppy per day but can have lifelong benefits. Of course a busy family home is naturally full of a variety of different stimulations which makes it a perfect environment for whelping puppies. Read more HERE.
