We have a German Shorthaired Pointer who was, to put it bluntly, out of control. The non-stop barking, whining, charging the front door, and jumping was too much to handle. Bark Busters was the best thing that we ever did for our dog and our sanity. I was beyond amazed at how easy Doug made the training, and how immediate the dog responded to the training. I cannot thank Doug enough for what he has done for our family. I finally have control back in my home, and like our dog so much better. I am beyond amazed at his complete 360 in less than 3 hrs. Again, thanks is not enough, and I have recommended this training to every dog owner that I know.
