Animal-assisted therapy (AAT) is an alternative or complementary type of therapy that involves animals as a form of treatment. It falls under the realm of Animal Assisted Interventions (AAI). AAI is general term that encompasses any intervention or treatment that includes an animal in a therapeutic context such as Emotional-Support Animals, Service/Assistance Animals, and Animal Assisted Activity (AAA). AAT contains sub-sections based on the type of animal, the targeted population, and how the animal is being incorporated into the therapeutic plan. The most commonly used types of AAT are canine-assisted therapy and equine-assisted therapy. The goal of AAT is to improve a patient's social, emotional, or cognitive functioning and literature reviews state that animals can be useful for educational and motivational effectiveness for participants. There are various studies documenting the positive effects of AAT reported through subjective self-rating scales and objective physiological measures, such as blood pressure and hormone levels.

Equine-assisted therapy (EAT) encompasses a range of treatments that involve activities with horses and other equines to promote human physical and mental health. The use of EAT has roots in antiquity, and EAT applies to physical health issues in modern form dates to the 1960s. Modern use of horses for mental health treatment dates to the 1990s. Systematic review of studies of EAT as applied to physical health date only to about 2007, and a lack of common terminology and standardization has caused problems with meta-analysis. Due to a lack of high-quality studies assessing the efficacy of equine-assisted therapies for mental health treatment, concerns have been raised that these therapies should not replace or divert resources from other evidence-based mental health therapies.

A therapy dog is a dog that is trained to provide affection, comfort and support to people, often in settings such as hospitals, retirement homes, nursing homes, schools, libraries, hospices, or disaster areas. In contrast to assistance dogs, which are trained to assist specific patients with their day-to-day physical needs, therapy dogs are trained to interact with all kinds of people, not just their handlers.
