About Us

Owner and Trainer – Marie Devaney Conyers

Marie-Cozy-Harry-OutsideHello and welcome to The Fundamental Dog, where we are dedicated to helping dogs and their people build relationships based on trust and understanding. I know from personal experience how frustrating it can be to love your dog but not be able to “control” him. For over a decade, I’ve studied with some of the leading experts in positive-reinforcement dog training, and I find great joy in sharing that knowledge with others.

As a volunteer with two national rescue groups (first Aussies, then Springers), I’ve fostered well over one hundred dogs – and they have been my best teachers! I’ve also taught dogs in shelters, provided training to shelter adopters and volunteers, and counseled foster parents and adopters around the country.

As a Karen Pryor Academy Certified Training Partner, I completed an intensive education and was required to demonstrate a high level of skill in training dogs as well as teaching dog owners. For more info about this certification, visit http://www.karenpryoracademy.com. I’m also a member of the Association of Pet Dog Trainers and the International Association of Animal Behavior Consultants. I strive to keep current with advances in dog training through seminars, workshops, books, and professional trainer practice and discussion groups. View my list of my educational activities.
