Anthrozoology (also known as human–non-human-animal studies, or HAS) is the study of interaction between humans and other animals. It is a modern interdisciplinary and burgeoning field that overlaps with a number of other disciplines, including anthropology, ethology, medicine, psychology, veterinary medicine and zoology. A major focus of anthrozoologic research is the quantifying of the positive effects of human-animal relationships on either party and the study of their interactions. It includes scholars from a diverse range of fields, including anthropology, sociology, biology, history and philosophy.
