A literary field companion into the heart of the horse-and the soul of connection. Herd Wired takes readers on a transformative journey into the equine mind, exploring how horses experience the world through their senses, emotions, and social bonds. Internationally recognized equine behaviorist Kerry M. Thomas, founder of Herd Dynamic Profiling(TM) and Sensory Soundness(TM), distills more than three decades of research into an accessible and thought-provoking guide for horse owners, trainers, breeders, and enthusiasts. At the core of Thomas's work is the belief that every horse is an individual with a unique psychological "wiring" that shapes how it perceives, processes, and responds to its environment. By understanding herd dynamics-the emotional and social framework that guides equine interaction-readers gain the tools to see horses not just for what they can do, but for who they are. From decoding the subtle language of the herd to examining how sensory processing influences training and performance, Herd Wired bridges science and storytelling. Along the way, Thomas highlights real-world applications: making better breeding decisions, choosing training strategies that fit the horse's natural tendencies, and developing deeper partnerships built on empathy rather than control. More than a manual, this is an invitation to reimagine the relationship between horse and human. Herd Wired challenges readers to step beyond traditional views of training and horsemanship, opening the door to a more compassionate, effective, and rewarding connection. Whether you are a competitor seeking an edge, a breeder looking to preserve temperament, or simply a horse lover searching for greater understanding, this book will change how you see your horse, your role, and the emotional language that unites you.
