“Lorrie is a fantastic teacher.  She is so patient, non-judgemental, and encouraging.  Lorrie does a great job explaining the steps we needed to do in a clear manner.  It is obvious how much she likes her job and how skilled she is at it.”   Debbie Zimmerman, Dix Hills

"I would certainly recommend Happy Dog Training to any new dog owner. We trained in a small class and truly believe that I received the skills that I needed to communicate clearly with Nala. I also would like to thank Lorrie for a calm attitude and patience during each sessions. In such a short time, she knew each dog strengths and weaknesses and could coach us effectively."
