We hired Dave to work with our puppy Copper who was having severe issues with going to the bathroom outside. We got a few sessions with him and after only the first one we had a complete 180 with Copper. She began going outside automatically. He was extremely good with her and he never failed to answer any questions we had at any time. He took all of our problems and gave us a way to work on them. He impressed us and we were very pleased. Thank you Dave!
