We were at the end of our rope and out of options--the dog had to change or had to go. We were pessimistic about training as we had tried numerous other training techniques and nothing had worked but thinking of getting rid of Ferguson put us in tears. After just one visit, we had a different dog. After two weeks, not only are we happy, but our dog is happier as well. It is now a joy to go for walks. Ken and Lynne took all the time needed to make sure that we understood what to do and also why we were doing it. Bark Busters saved us our dog.
