Preface About 10 years ago, I was training my new yellow Labrador retriever, Spunky. The method of training involved using a clicker. The sound would signal to Spunky that he correctly obeyed instructions. The clicker worked like a charm. There were no emotional “good dog” or “no” comments. I would just click to acknowledge that Spunky did as asked. Amazed at the effect, I wondered if I could apply the same or a similar method to the athletes on the track and field team I coached. After I explained to the team why I wanted to try the method—to mark proper form—I began my experiment. What follows is a description of my experiment and the often astonishing results of removing emotional comments from training in favor of a nonjudgmental marker. What information does the author provide in the preface? background information on yellow Labradors and an explanation of track and field background information on clicker training and an idea of what will be presented in the book background information on clicker training and a comparison of dogs and runners background information on the author’s coaching career and what will be presented in the book
