Wow!! We didn't think training could be easy and fun. We have four dogs, two cattle dog mixes and two very strong willed doxies. We have tried so many techniques to correct barking door behavior and leash aggression, all with little success. Risto, our Bark Buster trainer, identified the mistakes we were making and taught us how to change our behavior to make training our dogs a successful and positive experience!!! Not only did they not bark at the door, they actually stayed back and didn't jump either. I wish I had a better word to express our amazement that we were able to do this so quickly. Thanks Risto for giving us a better way to approach training our girls. We look forward to the doorbell and the walks.
