The techniques explained and demonstrated by Chris were not only easy to follow and understand, but they were also extremely effective. We observed noticeable results by the end of the training, and we continued to reinforce, correct and reward positively. Today, barking is under control and door manners have been learned. All techniques that were explained and demonstrated gave us an excellent glimpse into the dog world. Bark Busters techniques are easy to understand, and they work! Chris taught us how/what dogs interpret, understand, and react/respond to and what we needed to do to make lasting positive changes. Extremely interesting and enjoyable. We have recommended Bark Busters twice: 1 - To the lady who cuts our hair. She has an aggressive dog, and we recommended Bark Busters to help her out; 2 - To my brother and his wife, Erin. They have a golden retriever who pulls on the leash and snaps at Erin.
