Transformational! David w/K9 is an amazing trainer and exceeded our expectations. Our dog Duke is a 1yo Standard Poodle (75 pounds) with a ton of energy and prey drive. Duke spent 2 weeks with David in a board & train program and came home an absolutely different dog. One of my fav parts of the training was the 2+ hour handoff, where David did a knowledge transfer and made sure Duke was responding to all my commands and I had a high degree of confidence I could continue on my own. Our goal for Duke is to be an exemplary doggy citizen and this was the best investment we could have ever made. 10/10, highly recommended.

We used David to help out with our 1.5 year old golden retriever. We had issues on walks with him jumping on us and reactivity to oncoming dogs. Not only have we seen major improvements, our dog was able to learn new skills we would have never thought he was capable of. We would highly recommend Good K9 if you need any help with your dog. The investment has saved a lot of frustration and made our walks much more enjoyable.

I'm so happy to have found Good K9!! I have a year and half old German Shepherd, Bud, who I've been training and taken to trainers since he was a puppy. Recently he was showing a lot of reactivity towards other dogs and people. After trying another trainer local to me and having no luck in solving the issue I called Good K9. Andrew was very knowledgeable and was super quick to get a eval in. While in the board and train he sent me frequent updates and videos on how my dog was doing and progressing which was so nice and reassuring. When I picked Bud up the videos rang true and his reactivity compared to before was like night and day. Bud could now walk throw barking dogs and groups of people without caring. Andrew even got him to reach my goal of an off leash heel! Most importantly I can truly see how much he and the company cares for the dogs in their care and I felt at ease that my dog would be safe with them. Andrew treated and trained my dog as if it were one of his pups and I'm so grateful. If you have any doubts on where to go - take. your. dog. here.
