Can equine communication via audible exhales improve the welfare of therapy horses? – A pilot practice project

Abstract

Abstract Background: Human-animal interactions in human services are on the rise, with an increased focus on the welfare of animals involved as well as on client safety. Based on scientifically based training methods, it has been proposed that horses involved in therapy settings could benefit from learning proactive strategies to reduce stress. One possible strategy is audible exhale communication (AEC). Inviting horses to actively use this strategy with humans could enhance the welfare of horses in equine-assisted therapy (EAT), thereby increasing client safety. Methods: A pilot project was conducted to test the feasibility of training 20 therapy horses to use AEC as a veto signal for an activity, while therapists responded to the signals. The number of audible exhales from the horses was compared between the initial and final training sessions. Furthermore, we tested whether age, years of training experience, and therapy experience served as moderating variables for the outcome. Additionally, qualitative observations were made by therapists working with the horses. Results: It has become apparent that training the horses to use AEC was successful. After 6 months of training, the horses showed a significantly higher number of audible exhales than in the initial training session, with a large effect size. Neither age nor years of training or therapy experience was found to be a moderating variable. The horses were eagerly engaged with newly acquired tools. These showed fewer indications of stress, greater sense of relaxation, and more positive emotions. Conclusion: Based on the findings of this pilot study, training horses to use AEC might be a feasible approach to reduce stress in horses working in therapeutic settings, increase client safety, enhance human-animal relationships, and open up new possibilities for improving the therapeutic process. This method is applicable to all horses, regardless of their age, training level, or experience in therapy. For future research, it would be interesting to replicate and extend the approach by addressing the aforementioned limitations and using a randomized controlled design to investigate the introduction and impact of AEC in a therapeutic setting and to gain more comprehensive insights.
