I was beginning to think there was no hope for my 2-yr-old shih tzu. My other dog is very mild mannered, but Belle would go after anyone who went by our house. Before calling Bark Busters, I read all the testimonials and thought it was too good to be true, but after one lesson with Annette, I was convinced this would work. What I like about BB is the guarantee, the fact Annette came to the house and worked on my problems with Belle not like in a class. I was surprised in less than 6 weeks Belle is a delight and we are not embarrassed to have people over any more. Thanks, Annette.
