Doug made the instructions very easy to understand. He clearly has a passion for what he does, which translates into an energy that made the process fun. Lucy responded immediately to the training, particularly related to walking correctly, "take it/leave it", and not getting aggressive with Doug's dog on the second visit. The process is fun but also a little stressful (since the training is really focused on us and changing our behavior with our dogs), but that is just the reality of having to learn a new mindset and is no fault of Bark Busters. I did enjoy the quick results, and have already recommended Bark Busters to two co-workers. Doug was very professional and follows up appropriately.
