Before you can proceed to any basic training of your dog, you must teach him to focus. It is a good idea to begin your initial training by taking your dog into a quiet and familiar environment where he will be least distracted, thereby obtaining the greatest level of focus. Focus is the single most important command to teach your dog. If your dog is looking away from you, he is listening to what he is looking at. Distractions are a large part of life, and you need to teach your dog to ignore them and pay attention to you.
