This program is very simple! Patrick was very thorough and explained everything plain and simple. I noticed my dogs' behavior change immediately! My dogs (Lexus, Titan, Drakon and Saber -- American bull terriers) and I seem to understand each other now. I like you don't have to be physical at all with your dogs. The dogs react very well to these methods. The training experience was very interesting. To see how dogs look to the pack leader, it is very easy to maintain leadership. I would recommend Bark Busters. I now look at my dogs in a whole new way. Our relationship will be better now we can communicate!
