2020 Working Dog Conference Speakers

Keynote Speaker

Prins_Simon with DogsSimon Prins -Simon Prins ACT!

Simon Prins is known for introducing operant conditioning to the Police K9 training world. For the last 25 years, he has skillfully trained and purposed dogs for special operation missions and has mastered the art of using robotics and sensors with dogs to perform such tasks successfully. Simon has titled and trained countless dogs and trainers from special units across the globe and firmly believes that science can significantly improve our work with animals. Simon Prins is a speaker, author, innovator, animal trainer and behaviorist, and is currently working with the Netherlands Police Agency. Simon's interest in canine work peaked when he was on a hunting trip with dogs in1989. He was impressed with their abilities and started looking into opportunities to work with dogs. Not soon after, he joined the police force and became one of the youngest patrol dog handlers. In 1996, he was asked to set up a special K9 project incorporating the use of radio guided camera dogs. In the years that followed, he implemented programs such as hard surface tracking, laser guided attack dogs, and various levels of detection to name a few. In 2002, Simon created the Urban Search and Rescue Unit selecting and training 16 dogs and handlers to work alongside him in search and rescue operations. In 2006, he started to incorporate the use of electronics with dogs even more, outfitting them with sensors and training them to carry small robots into operations. In the years since, Simon has written countless training protocols and has developed a number of innovative training apparatus. He believes that following protocols, collecting data and educating trainers has been the key to his success, as well as replacing traditional punishment training methods with operant conditioning techniques. Simon travels the worlds extensively teaching working dog trainers how to do the same. 

Conference Speakers

Jeanne Brock, Working Dog Conference

Jeanne Brock, LVT - Canine Performance Sciences, College of Veterinary Medicine, Auburn University

Jeanne Brock has had a lifetime long interest in dogs and their abilities. This evolved into training dogs, first for AKC obedience and tracking trials, then schutzhund training and competition. Tracking, scent and detection work were always her main interest and led to training for search and rescue and cadaver recovery. Beginning as a "hobby", my interest grew to become my profession. For many years, training and working dogs (and handlers) in canine detection - flammable liquid detection, drugs and explosives - in the public and private sector was my work. In 2003, Jeanne joined Auburn University's Canine Detection Training Center as a senior instructor and trainer, teaching classes and training dogs for various scent work including drugs, explosives and chemical detection. During this time, she was instrumental in development and training of the Vapor Wake Dog, now a patented training process. In 2004, she also became manager of the breeding program, initiating and developing the Auburn Dog Prison Program as an integral part of the breeding program. Retiring from full-time work with Auburn and the Canine Performance Sciences program, she continues working as consultant/advisor to the Auburn Dog Prison Program. In addition, she works as a consultant to VaporWake K9, continuing to teach and evaluate dog and handler teams in the field.

Bob Dougherty and K9 partner TangoBob Dougherty, Law Enforcement K9 Training Coordinator - Penn Vet Working Dog Center

Bob Dougherty retired after 31 years with the Cheltenham Township Police Department in Montgomery County, Pennsylvania, 28 of those years were spent as a dual purpose K9 handler and eventually the specialized units trainer. Bob and his three canine partners graduated from the Philadelphia Police K9 Academy between 1988 and 2014.  Bob is a long-time member of the United States Police Canine Association (USPCA) and the Editor of their publication “Canine Courier”. Bob has certified all of his partners in numerous police dog trials and certifications to include one USPCA National Police Dog 1 (PD1) field trial. Bob is a certified USPCA Regional Patrol Trainer and Detector Trainer, Regional Judge for PD1, National Detector Judge, and has attended numerous training seminars to include several decoy seminars over the years to learn how to “help” both dogs and handlers be their best. Open to all types of training styles and philosophies for the betterment of training police dogs, as well being open to training styles from various police, sport and civilian dog trainers, Bob’s personal moral code is to never be cruel in the training of dogs in general, and specifically in training police working dogs. Bob’s approach is one that first looks at each dog as individualistic, focuses on establishing a solid foundation of training those basic skills necessary for young dog’s to be successful, and to remove the conflict which can occur between a dog and handler due to harsh and often premature physical corrections. Bob believes that trainers need to be actively involved with training dogs, and not just sitting back evaluating from afar.

RotheCarl Rothe, Senior Instructor - Puppies Behind Bars

Carl Rothe is the senior instructor for Puppies Behind Bars (PBB), a non-profit organization that trains prison inmates to raise, train and care for puppies that will become service dogs for wounded war veterans and first responders as well as explosive detection canines for law enforcement. Mr. Rothe took his love and passion for his own Labrador Retrievers, and began his career in dog obedience training. This lead to his employment at a nationally renowned guide dog school located in the New York metropolitan area. It was here that he worked and received formal training and eventually took an instructor position with PBB. Now as the Senior Instructor his duties include the training and instruction of new staff as well as opening and preliminary instruction for the program in new correctional facilities. Mr. Rothe also oversees the breeding program which is responsible for producing 35 to 45 puppies per year. Founded in 1997 by Gloria Gilbert Stoga, PBB has become a world leader in prison dog raising programs. The quality of the dogs produced is second to none, but equally important is the effect the program has on the inmates who care for the dogs. The puppies live in prison with their ‘puppy raisers’ from age eight weeks until eighteen months. As the puppies mature into well-loved, well-trained dogs their raisers learn what it means to contribute to society rather than take from it.

Bridget Stewart-Working Dog Center

Bridget Stewart-Beardsley, Trainer - Penn Vet Working Dog Center

Bridget’s interest in canine behavior started at a young age. She began working dogs in 4H with her Rhodesian Ridgeback and as a puppy raiser for The Seeing Eye. Through these experiences she learned about puppy development and learning curves. Throughout college she worked at a local animal shelter as a trainer and behavior evaluator. She worked with the shelter dogs teaching obedience, loose leash walking, and kennel manners. She also worked with staff and volunteers teaching positive training methods and canine behavior and body language. This helped the shelter team facilitate better matches with potential owners which led to more successful adoptions. Bridget attended Delaware Valley University and graduated with a Small Animal Science degree with a focus in animal behavior. The school provided a hands on learning program and she was able to successfully train a variety of animals from chickens to horses. After graduating, she began interning at the Working Dog Center where she learned about drive, scent work, and the training of working dogs. Now as one of our full time trainers Bridget says she is continuing to learn and improve her skills every day and that she “absolutely loves her job!” Bridget also offers her expertise to the public through evening classes offered through the Working Dog Center.

Scott Thomas, Consultant - AKC Detection Dog Task ForceScott Thomas, Working Dog Conference 2020

Scott Thomas became a federal employee of the TSA Canine Training and Evaluations Branch in 2005. He was the program manager of the breeding program, which produced more than 500 dogs specifically bred for detection work. This effort required the application of genetic quantitative trait selection, continual behavioral assessments, the understanding and use of exercises to control epigenetic expression, and maintenance of good canine health within the breeding colony. He oversaw two Department of Homeland Security Science and Technology Directorate research contracts to improve behavioral metrics, enhance development, identify genetic markers of success, and trans-generational epigenetic effects. Due to economic restraints, the TSA Canine Breeding and Development Center’s efforts were discontinued. At that point, Scott oversaw the contracting efforts for canine procurement for single-purpose detection dogs. Scott began his career in animal husbandry and training in 1983 as a dog obedience instructor and boarding kennel operator. He then spent five years as a veterinary assistant and worked in a variety of animal-related jobs including dolphin and sea lion training, exotic animal habitat design, eco-tour guide of Carolina coastal habitats, and exotic bird presentations. He currently serves as consultant to the AKC Detection Dog Task Force and manages the AKC Patriotic Puppy Program.
