Keith was our last resort before considering finding a new home for our 7 month old shepherd mix rescue who was taking over our house and our lives. His separation anxiety, reckless tail chasing, jumping, nipping, chewing, and overall bad behaviors was restricting us from leaving the house and having guests. Thankfully someone recommended Bark Busters to me and was raving about the improvement in her dog and I did some research. Keith responded to my inquiry almost immediately and after hearing we wouldn't need to use treats anymore and no shock collars were necessary we knew we had to try it if we wanted to make things work with Guinness. Bark Busters saved us and Guinness from a truly miserable situation and made living with our dog bearable. We now can enjoy his company, leave the house without him whining/crying/barking, and walk him wonderfully on a leash. We would recommend Keith and Bark Busters to anyone because they truly understand dogs and know how to get through to them. Thank you so much Keith!
