We observed noticeable results by the end of the training!! It felt like the television show "The Super Nanny" where the professionals come in and assess the situation and teach you methods for gaining control, assign homework and leave things in better shape than when they arrived. We found the training experience absolutely enjoyable and had a great time. We will definitely recommend Bark Busters to friends and neighbors because it's fun and effective. Truly, if I hadn't seen the changes that occurred in the first three hour training session, I wouldn't have believed it!!!
