As Sheldon was approaching five years old, his reactivity was getting out of control. We reached out to Sam Ivy and were matched to Christian, and our experience has been incredible. Christian really took the time to understand the issues we were experiencing and methodically worked with us. We are five weeks into the program and Sheldon is a different dog - confident, obedient, and even more playful and happy. We highly recommend Christian and the Sam Ivy program!
