The aim of our project is to develop an ethical evaluation tool for Equine Assisted Therapy that considers the welfare and the dignity of both horse and human. This tool will facilitate the evaluation of a practice giving information on the good life of both the horse and the human. If the practice for evaluation is not in conflict with the different parts of the tool, a basic level of ethical quality is reached. If the practice facilitates several of the different parts of the tool, the level of ethical quality will be higher. This tool will be easily applicable to current practices as well as in evaluations of forthcoming practices.
