Patrick explained the techniques extremely well. Additionally, he explained the logic behind them, which made it very easy to comprehend and apply. My dogs (three of them) comprehended the guttural BAHHHH tones and the high-pitched ones to differentiate between corrections and praise. The natural training techniques made sense. Understanding pack mentality is key to training dogs from a human perception of relating as a dog. The lesson was very enjoyable, and I learned a lot. Patrick is an excellent communicator/therapist. He should be commended for doing such fine work. I think many dog owners are equally frustrated with unwanted behaviors, but do not understand pack behavior or dog communication. They may also not understand appropriate techniques (but Bark Busters can fix that).
