Trainer - Heidi Moreau


Heidi is a graduate of CATCH training academy earning the title Certified Dog Trainer (CDT). Heidi began training dogs at her local shelter while volunteering. Many of the dogs became better candidates for adoptions simply by teaching them a few basic obedience skills. She realized how rewarding it is to help dogs and dog owners and wanted to do more.

She has experience at getting puppies started in their training to be service dogs. She also works at White Oak Animal Hospital Training Center training dogs and managing dog play in Stafford County.  

Heidi has two rescue dogs of her own, Autumn, a Staffordshire/Bulldog mix and Meeko, a through and through mutt. She is a voracious learner; learning as much as there is about dog training by attending workshops, seminars, classes and shadowing experienced trainers.

Heidi loves taking her dog Meeko to dog sport classes. Her goal is to compete at Rally trials soon. She keeps Autumn busy with fun Nosework games and teaching her tricks such as spin, kiss and other fun tricks she can show off. Heidi also takes her dogs on regular hikes in the Shenandoah mountains, National Forests and different parks in the area to keep her pups exercised and happy. Heidi never misses a training opportunity with her own dogs, it is part of her daily routine to add just a few minutes of training to maintain what her dogs have learned.
