I think this method of training is so much better than physically discipling one's pet and hurting them rather than helping to change their behavior. Katherine made it very enjoyable and was very knowledgeable in the course of the training. We really had a blast working together with her. Granted we still have a ways to go with our training. My husband and I noticed immediate results in our dogs behavior. She was very thorough in her explanation and gave us many opportunities to try out the techniques while she was here. I will definitely recommend Bark Busters to any and all of my friends that have problems training their dogs. Thank you for the wonderful suggestions, training, tips and techniques.
