I finally had enough of constantly worrying about my dog, Allie, and being nervous whenever anyone came over. It was great, since I had the lifetime guarantee from a previous trainer with Bark Busters - it was totally free! This time, I followed all of the advice the trainers gave me, and within a few weeks, she was calm, happy and friendly -- the same dog whose family referred to as "killer" due to her aggressive barking and behavior in the past! I never thought I would have a dog who would let strangers pet her. She hasn't snapped at anyone since the first day James and Michelle came and has even started enjoying the company of other dogs. I am completely in love with my dog again, and so is everyone else!
