We were amazed! We had results in the first 10 minutes of training with our 5-month-old golden retriever mix. After our first 2-hour lesson, our dog was not jumping, was able to walk at our side without pulling in the leash, sitting, staying and coming on demand. Doug was wonderful and helped us understand "how a dog thinks." The next morning, our dog was still obeying and following directions. We are going to continue the program 10-15 minutes a day as instructed and look forward to showing Doug on his next visit how well the program is working for us. I would highly recommend Bark Busters!
