Thank you, Gerard and Bark Busters for helping us with Bruce's (our dog) anxiety and territorial issues! Our 7 year old rescue sheltie Bruce was the perfectly behaved dog for 3 months until... he started assuming control over us, our guests and our place. The behavior was especially difficult when a visitor would make a movement to walk away, which seemed to invoke his herding instincts, including barking, circling and nipping. When our son returned to live with us for a while, we could not even have them in the same room for fear of this behavior. Gerard of Bark Busters came to the rescue and taught us how to apply corrections and their appropriate timing. Bruce responds well to the training tools which in turn provide us with a great level of confidence. Bark Busters methodology allows us to continue reinforcement as the pack leaders, and better still, Bruce seemed to enjoy and relax in his role as pack follower again! Our son can now move around freely. It does take a little work, but having a well behaved dog is priceless.
