For those folks who are skeptical and hesitant to believe this training works...like we were...well..it does work and you should just go for it! You'll be amazed and you'll join all these people as believers, too. Our dogs (all four), Bailey, Pixie, Cubby, and little Kipp, finally get what we want them to do. There was amazement from our neighbors when all the barking immediately stopped. They wondered where our dogs went and if we still had them. Also, the lifetime guarantee speaks for itself. What other dog trainer will give you that? You won't be disappointed and you will learn so much. It is well worth the small effort to enjoy your dogs for a lifetime, and the dogs are so much happier too! Everyone should get this training when they first get their dog!
