ABOUT HEATHER MAZAHRI

The heart behind Z Dog Training Academy

A mom, Certified Professional Dog Trainer, and lifelong student of behavior. For me, dog training isn’t just a job, it’s a calling rooted in connection, compassion, and curiosity.

For over 20 years, I’ve helped families turn barking, pulling, and chaos into calm homes and happier walks. But what truly drives me is growth- in dogs, in people, and in myself. Every year, I take continuing education courses in canine behavior science and positive training methods to ensure I’m always learning, evolving, and offering the most effective, ethical techniques possible.

As a mom in recovery, I understand the beautiful messiness of real life. I know how hard it can be to balance structure and grace, and that’s exactly what I bring to every training session. My approach is science-backed, compassion-forward, and built to fit into busy family life (no harsh methods, no unrealistic routines, just real progress that lasts).

The “Z” in Z Dog Training Academy comes from my two kids, Zane and Zoey, who remind me daily that patience, kindness, and consistency create the most meaningful transformations - in dogs and in people.

TESTIMONIALS

We rescued our dog Teddy very young and almost immediately ran into challenges that we now know stem from the high-energy breeds he comes from. We almost didn't know if we could keep him at one point.

Heather was a strong and calming guide through the intensity of those early puppy days. Today, because of Heather, Teddy has fully integrated into our home and hearts. Heather's training courses gave us the tools as handlers to respond to Teddy's energy thoughtfully and corrected the behaviors we struggled with the most. Her follow up with guiding homework and the support through phone and text was priceless.

We fully intend on continuing working with Heather through day camps and boarding because she is worth every penny! She is a great trainer with excellent communication skills, but more importantly a great person who loves dogs.
