An increased interest of animal-assisted interventions (AAI) can be observed within clinical practice, even though it is still not entirely clear how the presence of an animal contributes to the outcome of a treatment. One theory maintains that the presence of an animal influences the relationship between health-provider and patient, which then in turn affects the outcome of the treatment. To investigate this theory, this study will combine AAI with a placebo intervention, as placebo interventions offer the basic form of intervention working through relationship and expectancy. The effects of the presence of a dog will be assessed with a standardized experimental heat pain paradigm (TSA-II) in a randomized controlled trial in healthy participants (N=128). After a baseline measurements of heat pain threshold and tolerance, participants will be randomly assigned to one of the following four conditions: a) analgesia-expectation, no dog present, b) analgesia-expectation, dog present, c) no-expectation, no dog present and d) no-expectation, dog present. The dog will be introduced after randomization. Expectancy will be induced by a deceptive cream which is said to helps against pain. Afterwards, posttreatment measurements will be conducted and participants fill in questionnaires about their perceptions of the experimenter.
