Remembering Karen Pryor: The Legacy of a Trailblazer Who Ignited a Global Training Revolution

With profound sadness and immense gratitude, we honor the life and legacy of Karen Pryor, a true pioneer in the fields of animal behavior and positive reinforcement training. Karen’s groundbreaking work revolutionized how we communicate with animals—and each other—leaving an indelible mark on science, education, and the lives of countless species around the world.

Karen was born on May 14, 1932, and from a young age she exhibited a boundless curiosity about the natural world. Having spent her childhood summers collecting and observing butterflies and minnows, Karen’s innate curiosity and keen observational skills would shape her future work, creating the foundation for a lifetime of innovation and discovery. After earning her degree in biology from Cornell University, Karen began her career in marine mammal training at Sea Life Park in Hawaii, where her revolutionary methods first took form.

In the 1960s, Karen’s work with dolphins became the cornerstone of what would eventually be known as modern clicker training. Using a small handheld device to mark desired behaviors, she refined techniques rooted in operant conditioning, transforming these scientific principles into humane and effective training methods. Her groundbreaking book Don’t Shoot the Dog: The New Art of Teaching and Training remains a seminal work, widely regarded as essential reading for trainers, educators, and anyone interested in behavior change.

Karen’s seminars and writings had a profound impact on how we understand and interact with animal intelligence. She challenged traditional views, presenting animals not as creatures that merely react to stimuli, but as sentient beings capable of complex learning, creativity, and problem-solving. As Karen put it, “When you see an animal’s eyes light up, when you see an animal that comes zooming out to do its clicker work—and it’s an octopus or a shellfish—it’s remarkable, really. We just set them up and let them show us.”

Karen’s work in writing and publishing led to the creation of Karen Pryor Clicker Training (KPCT) in 2000 with business partner, Aaron Clayton. With Karen's inspiration, the organization catalyzed a community of positive reinforcement enthusiasts dedicated to teaching Karen’s principles and methods and advocating for their adoption across various settings—from companion animal training to competition environments and working animals, including assistance and guide dogs. KPCT became a leader in effective positive training methods, publishing books and other training resources, offering training products, hosting ClickerExpo conferences, and establishing the Karen Pryor Academy for Animal Training & Behavior (KPA).

The ClickerExpo conferences were the first training and behavior conferences of their kind, bringing together trainers, educators, and behavior enthusiasts to share knowledge, techniques, and innovations in positive reinforcement training. The conferences have inspired countless collaborations and continue to attract attendees from around the globe.

The Academy’s flagship Dog Trainer Professional education program has certified more than 2,600 canine trainers worldwide, establishing a network of professionals who continue to uphold Karen’s vision. Through her championing of education and innovation, Karen empowered thousands of trainers and educators, leaving an enduring legacy. Thanks to Karen, positive reinforcement isn’t just another way to train animals—it is THE way. You’ll find a clicker in almost any pet store, and a treat pouch on almost every pet guardian. She set the wave of change in motion, and it's bigger than she ever envisioned.

Karen’s influence extended beyond the animal training community. She was a consistent advocate for the benefits of positive reinforcement in many areas of life, from parenting and teaching to corporate training. Through KPCT, Karen helped launch TAGteach, which extended the principles of clicker training into more areas of human education and training.

Karen’s work proved that kindness, clarity, and consistency foster trust and understanding across species. She taught us that even the smallest moments of communication—a click, a treat, a shared understanding—can lead to profound connections. She reminded us to celebrate every step of progress, no matter how incremental, and to approach each interaction with empathy and curiosity. Karen showed us that we can overcome challenges by finding something to reinforce, however small, and building from there. Through her example, we learned that when we observe life through the lens of a positive trainer, we are always seeking, discovering, and learning from the good in this world. Perhaps most importantly, Karen showed us that the world is a much better place when we choose empathy, kindness, and respect over conflict and division.

Karen’s love for the world around her endured throughout her later years, even as she lived with dementia. She spent her days collecting stones, observing cloud formations, and marveling at the natural beauty that surrounded her. Her children affectionately referred to these moments as her "dementia poetry." “Look,” she once said to her son, “the clouds are inventing themselves.” Even in her final years, Karen found positivity in the simplest moments, embodying the wonder and creativity she had always embraced.

Karen’s parting words in an interview about her retirement from Karen Pryor Clicker Training resonate deeply: “I’m not done yet.” Truly, she is not. Her teachings and vision continue to inspire the way we communicate, connect, and find joy. Karen is with us—always—in our moments of discovery, in the harmony we create with our animals, and in the beauty that surrounds us. She is with us when we experience those “aha” moments with our animals, when we walk through the woods and pause to observe a songbird or appreciate a beautiful cloud formation, or when we appreciate a sunset in its full glory. Her teachings can be found in the fields, the mountains, the trees, and the clouds. They are beneath stones, in the depths of murky ponds, and within one another. Karen’s legacy lives on in every wagging tail, every joyful click, and every moment of connection shared between people and animals.

Karen is survived by her children, grandchildren, and a global community of admirers who will forever be inspired by her wisdom and generosity
