Human-horse relationships take the central place in this edited collection examining the horse’s perspective by asking: How are human-equine relationships communicated, enacted, understood, encouraged, and restricted? The contributors apply varied disciplinary methods as they emphasize comprehending horses not solely in terms of their functional uses, but also as impactful participants in relationships, whether more—or less—equally. By exploring the “who” of horses, The Relational Horse offers a better understanding of horses’ lived experiences and interests within the worlds they share with humans, and a way forward for human-equine studies that more equitably represents the horse in those shared worlds.
