Artículo de investigaciónHorses currently play a leading role in many leisure events worldwide. However, their involvement in leisure activities raises various ethical questions. Based on a posthumanist approach, this study sought to explore the use and treatment of horses in a leisure event in Mexico. A participant observation method was adopted to conduct the research, revealing that horses become quite instrumental and commodified for humans, fulfilling intersecting entertainment, economic and cultural purposes. These results thus provide evidence of the prevailing anthropocentric and speciesist nature of horse-human interactions in leisure events. The findings include that, when horse-human relations become highly commercialised and are institutionally recognised as cultural heritage, a complete embracement of posthumanism is needed to dissolve basic horse-human dichotomies, but this remains a utopian ideal in tourism and leisure practices.
