What Clients Say

“Denise Mazzola is one of the best, if not the best, dog trainer in the country. When I first adopted my dog, I called Denise to help me with his training. He had many issues to address: Digging, jumping, not coming when called, chasing cars, pulling on leash, and barking whenever we were in the car together.

Denise came to my home, evaluated Luther, and then taught me how to get the behavior I want from my dog. Her training methods are gentle and produce excellent results quickly. For example, Denise broke my dog’s car-chasing habit in about 30 minutes. That was one-and-a-half years ago and he has yet to chase another car. There are no more holes in my yard, I can take him in the car, and even to the farmer’s market and band concerts. He is always well behaved. I can’t praise Denise enough, because I now have a very well-trained and happy dog. And that makes me a very happy dog owner.”
