We have a rottweiler/lab. mix that we got when he was almost 1yr. He was very exuberant, to say the least. He quickly became friendly with our family, but tentative around new people, especially men. We discovered Janie with Bark Busters on the internet. She has been able to help us zero in on problem behaviors. He is definitely a different and more controllable dog, today, than the day she first walked through the door. He is learning to walk more calmly on the leash, to sit and wait while I answer the door, to run free in our unfenced yard and come when called, and he loves the dog park. He is now two; we still have training we would like to do and she is always ready to help. We would strongly recommend Janie Fairchild to anyone.
