You may have your dog for 15 years! I'm in it for the long haul. I have found an amazing dog training method to address dog problems or just train a happy, calm and relaxed dog that is SUSTAINABLE. This is not a temporary quick fix training method that uses devises and force. This is a beautiful method that your dog will understand and in turn listen to you when you show him the way. This is a sustainable method for the life of your dog! A little effort now pays off 10 fold in the long run.
