We kept thinking that there has to be more to it than this: Linda's explanation/presentation was simple and easy to duplicate. Klondike was like a different dog after 3 hours! We've had Klondike only since Sept. 06, but have known him for almost 8 years, prior to mother-in-law passing away. People kept telling us to get a shock/bark collar to address behavior, but we didn't want to do that. Linda brought a relaxed air of professionalism, humor, and experience into our home and conducted an absolutely simple, but fantastically dramatic re-training for both us and Klondike. We would recommend Bark Busters without hesitation, having experiences Linda and the Bark Busters system in person, I believe that there is a way to teach an old dog new tricks! When we took Klondike into our home 3 months ago, we didn't know if we could live with him and his 8 year old behaviors. Linda changed that in 3 hours! Thanks, Linda!
