Colin explained the training techniques in a way that was easy to follow and understand, including some interesting points I'd never known, especially concerning respect. We observed noticeable results by the end of the first session; Archie was really starting to understand, tho still far to go. We were pleased with the natural training techniques used by Bark Busters, and especially that training is not food-based. We found the training experience to be very interesting and enjoyable; after watching June and Colin for a while it made us realize we could really do it. We would recommend Bark Busters, and are actually looking forward to practicing what we've learned before our next session.
