My husband and I were very skeptical about the effect the training would have on our dominant Golden Retriever. Within 30 minutes of the session, we saw a dramatic difference. It was amazing! About 95% of our laundry list of problems and issues were resolved with one session. Jumping on guests, eating and chewing clothes, jumping on furniture are no longer a problem. Our Golden comes when called, heels when walking and stays off the furniture! She is such a joy to be around now! We are excited to learn more and continue the training. Maril was extremely patient and helped us tremendously!
