Human–animal interaction (HAI) constitutes an important source of companionship, comfort, and support during times of illness, stress, loneliness, isolation, and trauma. Worldwide, research documents ways in which HAI stimulates verbal communication, increases empathy and morale, and facilitates social connections for support, belonging, recognition, and status. Researchers have also found positive associations between HAI and physical health. Pet ownership and/or engagement with therapeutic animals in animal‐assisted interventions (AAI) helps promote physical fitness, attachment, and the production of oxytocin while also lowering blood pressure, stress, and even mortality following a heart attack. Evidence also suggests HAI may contribute to reduced depression, anxiety, and loneliness for improved well‐being across the lifespan. Although interdisciplinary, most HAI research originates from outside of the health communication discipline. Scholars and practitioners interested in HAI hail from a variety of fields such as psychology, medicine, sociology, nursing, social work, and veterinary medicine. As interdisciplinary scholars and practitioners continue to solidify and clarify the benefits of AAI for people and animals, the HAI field will continue to flourish. Health communication scholars can contribute to this meaningful growth by developing evidence‐based interventions, advocating for AAI in public policy, and promoting professionalization of the field as a valued treatment modality.
