Overview
Oxytocin has been proposed as a neuroendocrine mechanism that may mediate the relationship between dog ownership and positive health outcomes and be linked to human-dog interactions and is thought to be a mechanism of interspecies bonding. While the role of oxytocin in human bonding behaviours and social behaviour, in general, is becoming well-established the role of oxytocin in human-animal interaction and Animal-Assisted Interventions (AAI) remains unclear. This research gap calls for more high-quality research investigating this possible neuroendocrine underlying mechanism to advance knowledge about AAI. If oxytocin indeed might be involved in interspecies bonding, intranasally administered oxytocin should not only enhance trust toward a human but also towards a dog.
