Maril made the training techniques very manageable for all family members. We were able to stop Jackson from jumping up on us by the end of the lesson. At first, the correction seemed silly to us, but it works to correct Jackson. It was interesting ...Although the first session was long, Maril was able to keep the interest of our 9 year old son. I would recommend Bark Busters training...It's fairly simple, it works, and it comes with a lifetime guarantee. I know that if I need help when Jackson gets older, Maril will come here to help us.
