Besides being a great guy David is an extremely talented trainer. We have a Giant Alsatian that we purchased in Germany and David has been working with us for the last 18 months or so. He has smoothed out little obedience problems that have made a world of difference to us. Our dog is very athletic and loves working with David as we continue his Schutzhund training.
