Karen is an active, leading spokesperson and teacher for effective force-free training across the globe. Her work with dolphins in the 1960s revolutionized animal training by pioneering and popularizing force-free training methods based on operant conditioning and the conditioned reinforcer.
Karen’s 40-year career working with and educating scientists, professional trainers, and pet owners has changed the lives of countless animals and their caretakers in zoos, oceanariums, and pet-owning households.
She is the author of six books, including Don’t Shoot the Dog!, the "bible" of training with positive reinforcement. Her most recent book, Reaching the Animal Mind, describes how to bring out the undiscovered creativity, intelligence, and personality of the animals in our lives.
