Christine really made an effort to understand me, my family and my dogs. She did a wonderful job using examples and stories to make the training relevant to us. The animals showed an amazing amount of attention after the first session. I did not want to resort to shock collars [for the sibling rivalry aggression]. I wanted this to be as easy as possible on my dogs. Training was enjoyable and challenging. But my hard work is paying off. I have already recommended Christine and Bark Busters to neighbors and friends because my pets seem happier.
