Horses in Company is an in-depth study of the social relations of horses in the wild. The book discusses how, during evolution, the need for collective defense against predators shaped horses characteristic behavior and reactions. It aims to help the reader understand how in domestic conditions, unnatural resource competitions and stress affect social relations, leading to widespread misinterpretation and misunderstanding. This radically new analysis of equine society is based on the author's first-hand observations, and opens the way to a new understanding of horses at both ethological and practical levels.
