This is our second experience with a trainer, we have had German Shepherd's in the past, this one is our fifth. We never have required a trainer with our other German Shepherd's, but this one has a mind of her own and does what she wants. We started with a training school when she was a few months old and it was training with treats, not a good idea. Our Vet's office had a brochure from Bark Busters and we called and got Chris, who our dog loves and listens and responds to very well, not so much with us, but we are working on it. Chris is very good, she answers all our questions and does not hesitate to come back to our home when we need help. And I wish we would had called on Bark Busters sooner.
