Equine and ovine ethology is the study of the species-typical behaviour of the domestic horse (Equus caballus) and the domestic sheep (Ovis aries): their social organisation, feeding, reproduction, and interaction with humans and housing [1][2]. Both are grazing prey species, yet their social systems diverge: horses form stable groups in which affiliative bonds and tolerance structure interaction, and this sociality is treated as an ethological need that domestication has not removed [3]. Sheep are strongly gregarious, and their behaviour and welfare vary with the housing system and with the social bonds available within the group [4]. For both species, the repertoire set out in these accounts is the reference against which housing and handling are judged [1][2].
