I LOVE Dave! I've known him 5 years and I still go back to him with questions, he is committed, responsive and just gets it. He has been my Go To trainer for my 5 year old Weimaraner Grace Olivia from the moment I brought her home - from the beginning he showed so much care and concern for my girl, and she is AMAZING because of his efforts to train me! I am getting a new puppy soon and you better believe he/she will be a Sit Happens graduate as well!
