The Adult Manners 6 week class really helped us bond with our dog and learn her strengths and weaknesses. Even though it was a group class, David made sure to speak to everyone individually about their specific concerns with their dog. Our dog is much more focused now and I feel like training her is actually possible!

David Roos was an excellent trainer and class leader. He listened to and addressed individual concerns, instilled confidence, and taught with clarity and joy. I learned a lot. My puppy did too. Highly recommend.

David was amazing!! We have 2 dogs each with their own issues.

The older dog was always in protective mode and would bark at other dogs. It got to the point that the older dog was very difficult to walk because he would sometimes be aggressive when he would see another dog. David was able to train our dog not to be in a conflict mode when he would see other dogs. He also helped my husband and I to be better prepared to prevent any encounter.

The younger dog was a puller. She could have been an Iditarod sled dog or at least that is how it felt when you would walk her. David once again worked his magic and showed us how to encourage her not to pull.

David has made our dog walking life so much easier. He was like Mary Poppins for dogs. He flew in saw the problem and corrected it (and us) immediately. Then he was off to help another family.

We both look forward to working with David in 2020.
