We do guarantee that if you follow our guidance, you will see results. We cant control what you do at home, we simply provide you the resources to train your dog, or fix your dogs behavior issue. This training does require some work on your part, outside of the training sessions. We have only had a few people not see the results, they expected in training, and all admitted and understood that it was due to lack of time on their part. In some cases we offered extra training free of charge to get those people caught up. We understand that life gets busy.
