Mission Statement:

Dog Dynamics, Inc. is committed to enhancing the human to dog relationship
by helping owners understand dog behavior from puppy-hood through geriatric.
We take the dog point of view to find out what makes your dog tick.
Through this understanding we can then choose the training methods that are appropriate
based on the dog’s behavior, temperament and your training goals.

Bonnie has professionally trained dogs since 1990 and is the owner of Dog Dynamics. Bonnie was a master trainer for AppleGate School for Dogs Inc. and American Detector Dogs. She is an evaluator for the American Kennel Club and is certified as a field representative for Paws With a Cause, an organization that trains service dogs for the disabled. She has worked as a canine field handler for the University of Reno and Desert Research Institute and for Working Dogs for Conservation Foundation. She volunteered for seven years as a trainer and member of the search and rescue teams for Contra Costa County Sheriff Department, California Rescue Dogs Association, and the California Office of Emergency services. She has conducted national workshops on training and deploying service dogs, dog behavior and obedience, reliable retrieving training, and the ethical use of training equipment.

She has helped countless individuals with challenging dogs, and has published manuals and papers on puppy headstart programs, beginning through advanced obedience, behavioral training, training dogs for human remains detection, and how to develop and maintain an athletic dog. Bonnie teaches weekly community group obedience instruction and offers private instruction as well. To continue her education she attends annual conferences, behavioral workshops and training seminars with canine trainers, handlers and behaviorists from the United States and abroad. She and her family currently share their home in the East Bay Hills of Northern California with Hendrix the barn cat, and two black Labradors: Quill who is a certified disability service dog, and Jet, who totally embraces her name.

Heather Petrocco

Heather has been a trainer since 2003. Her experience in working with students in our group classes has helped her understand a variety of training issues. Living with two dogs of her own, each with their very own personality, and the recent addition of her first child have given Heather new opportunities to apply her training experience to real life situations. Extended down stays and getting that very important "wait" at the door from her dogs has come in handy while raising a one year old daughter. Her expertise and dedication to the dog/owner team is a great addition to our school.
