I have a 6 year old American Pitbull that's great at home but a completely different dog outside of the house. He becomes anxious, excited, and has become aggressive towards other dogs. I wasn't sure if he would be too old to rehabilitate. But you can teach an old[er] dog new tricks! David came to the rescue. Immediately upon our first in-home consultation, he showed me how to stop my dog's excitement level from reaching a red zone and our first walk down the street went better than I had expected. I signed up for the 2 week book camp that included the 6ft leash training. When it came time to pick up the pup, I was floored at how well behaved my dog was. He was respectful and calm, even with the other dogs going off within and around the area. David is very professional and is truly an excellent trainer. I personally believe in his philosophy about dog training and all the tools he has taught me have become invaluable. I will have to continue to work with my dog, but I am so happy that David was able to steer us in the right direction towards building a stronger relationship with my dog and myself. Thank you David!
