David is amazing! I brought my dog in for a 2-week board and train to address issues with leash and dog aggression and he came back a totally new dog. Not only can I now take him anywhere without having to worry about aggression, but he is much more respectful and obedient in general. I was really worried before I brought him in that I would never be able to take him anywhere, but I'm not concerned at all anymore. David is so knowledgeable and helpful and he really took the time to talk with me and train me to work with my dog effectively in the future. He sent a lot of updates, pictures, and videos and it was amazing to see the progress made in just a few short weeks. I am really happy with my dog's progress and am so glad I made the decision to have him trained. I highly recommend Off Leash K9 Training and working with David in particular! He's very talented, honest, dedicated, and an awesome person.
