My dog was running out the door (into the street!) and barking all the time. I had gone to Petco for training and it did not work. I contacted Bark Busters to see if they could help me. Derek came to train my dog and gave me a lot of really good pointers. I am now working with her everyday and have seen huge progess. She rarely runs out the door and barking has gone away. She is even walking right next to me when I take her on walks. The training was worth every penny.
