At the end of the session, she reviewed the techniques again and wrote down the steps. Our biggest concern was the way Bear "attacked" the door when the bell rang. By the end of the session, he was sitting in his designated area waiting permission to approach. I took Bear to obedience over the winter where you rewarded behaviors with treats. Eventually, he got bored and full. I like the way he needs to respond to our voice and body language and gets rewarded with praise. Just amazing how he responds. I would definitely recommend Bark Busters to others.
