Jon has saved us so many times! Yzerman had failed two obedience courses before we called Jon. Thanks to Jon’s time, care, and knowledge Yzerman is the best dog. For reference, If there was a scale of stubborn dogs Yzerman was in the top 10%. Both my husband and I have owned several dogs in our lives without issue, but Yzerman was a doozie. Thanks to Jon, he is the sweetest dog ever. So well behaved. We took Yzerman’s sister Lidstrom to Jon immediately after getting her and she’s been perfect! We get compliments when we walk the dogs in the park about how well behaved the dogs are. I would highly recommend Jon with sit means sit. I have no regrets and will use Jon for our next dog.
