Animal Assisted Intervention (AAI) is a goal oriented intervention that intentionally includes or incorporates animals in health, education and human service for the purpose of therapeutic gains in humans. Animal assisted interventions incorporate human-animal teams in formal human service such as Animal Assisted Therapy (AAT) or Animal Assisted Education (AAE). Animal Assisted Activity (AAA) is the informal AAI often conducted on a volunteer basis by the human-animal team for motivational, educational and recreational purposes. AAI could be used for rehabilitation therapy and psychotherapy for patients with various symptoms. AAI uses animals, mostly dogs, to aid in healing patients holistically. Dogs have an overwhelming gratitude and exuberance for life and this effect on people is astounding. Furthermore, AAI has been researched and its effectiveness on patients' outcomes and healing is documented. With a soaring trend of the incorporation of complementary therapies into the mainstream of therapy and health care, animal-facilitated therapy has become a popular interest for the therapy team to integrate into a patient's plan of therapy. The purpose of this manuscript is to raise awareness about AAI and to familiarize readers with the concepts surrounding AAI so that they can be informed aids to clients who might benefit from the technique.
