Pete's explanations and descriptions made so much sense and his instructions were so easy to follow. My husband was skeptical and thought he was not tameable, but I had hope because he hasn't always been this aggressive. I am shocked at how quickly Bishop has responded to instruction. I am so ready for some training. Attempted to take him to the dog park last weekend (with leash)and he was looking to start some trouble. I am so looking forward to the day we can all (Husband, Sophia the Saint Bernard, Yukon Jack the Siberian Husky, Bishop the bully Boxer and myself) can enjoy a day at the dog park with putting Bishop in timeout!!! Wonderful, wonderful, wonderful. I am so pleased with the progress in such a short time!
