In the 1970s the US Military did a study of puppies and dogs in an attempt to determine what exposures benefit a dogs development. The end goal was to improve the performance of their military working dogs. The study found that certain simulations during the period of rapid growth, the third and 16th day of life, would aid in the development of neurological functions and improve the dogs over all neurological, cardiovascular and endocrine system later in life. This program became known as the Bio Sensor Program (or Super Dog programing colloquial terms).
