Professor of Surgery Emeritus at Cummings School of Veterinary Medicine at Tufts University in Massachusetts, Jackson provided "indisputable evidence, available for more than a decade, disproving the claim that domesticated horses need shoes." Jackson's book, Paddock Paradise: A Guide to Natural Boarding (2006), further advances the concept of using natural horse care to restore and maintain optimal health. Jackson has moved away from client work, his efforts are now directed into further written work, consultations, and the training programme known more by its acronym ISNHCP. Paddock Paradise and natural boarding This natural horse boarding concept was introduced by Jackson in his book, Paddock Paradise, A Guide to Natural Horse Boarding (Star Ridge Publishing). The premise of this boarding model is to provide safe, humane living conditions that use the horse's natural instincts, and thus to stimulate and facilitate movement and other behaviors that are essential to a biodynamically sound horse. Jackson concluded from his studies based on the behavior of wild horses, that domesticated horses appear thrive physically, mentally and emotionally if kept in an environment that takes into consideration the most basic elements of their natural world by situating and propelling them into forward movement. According to Jackson, who founded the American Association of Natural Hoof Care Practitioners (AANHCP) in 2002, the hoof is adaptively cross-linked to the nexus of natural behavior and movement and can be restored to its native integrity and soundness by putting horses in such a simulated natural environment. The paddock paradise model is unlike a traditional situation with stalls, small paddocks and/or lush green pastures (which Jackson calls "founder traps"). It is designed to encourage movement through the creation of a series of fenced paths with a quantity of various stimuli such as strategically placed feeding spots and watering holes that are incorporated within or alongside the track in order to activate curiosity or movement. Natural horse care practices include elements of natural hoof care, encouraging herd mentality, foraging for small amounts of food strategically available throughout the day, maintaining a watering hole near or at the source of drinking water, and behaviors related to horses as prey animals, relative dominance (pecking order), grooming, resting and sleeping behaviors.
