Verified by World Mental Healthcare Association

Pet therapy refers to the use of animals as aides in the treatment of mental and physical disorders. It usually involves a guided interaction between a patient and a trained “therapy animal”.

What Is Pet Therapy?

Pet therapy or animal-assisted therapy (AAT) 1 involves formal, structured, and goal-oriented interactions between animals and patients—helping the latter achieve certain treatment outcomes.

In most cases, pet therapy for the elderly, children, military veterans, and the mentally ill is used as an alternative or complementary type of therapy to treat depressive symptoms, anxiety, untreated trauma, developmental disorders, etc.


The term “pet therapy” was coined in 1964 by child psychologist Boris Levinson 2. However, as far back as 1792, the medical importance of pet therapy was first documented when British philanthropist and quaker William Tuke incorporated birds and animals in the treatment plan for people with mental health needs in his asylum, The York Retreat.

In the 1970s, Samuel Corson and Elizabeth O’Leary Corson 3, psychologists at Ohio State University, conducted the first empirical studies of canine-assisted therapy. They laid the groundwork for modern animal-assisted interventions.

Animal-Assisted Activities vs Pet Therapy

The broad category of animal-assisted interventions includes animal-assisted therapy (AAT), animal-assisted education (AAE), and animal-assisted activities (AAA). However, in most cases, people mistake animal-assisted activities (AAA) for animal-assisted therapy (AAT) or pet therapy.

Both types are unconventional therapy types 4 that include animals’ use in treatment and recovery. However, the two are not the same. Pet therapy or animal-assisted therapy (AAT) involves including animals as aides in psychotherapy.

AAT comprises a formal, structured set of therapeutic sessions that helps people reach specific goals in their physical or mental health treatment. AAA, on the other hand, involves more casual meetings in which an animal and its handler interact with one or more people for recreation or comfort.

How Does Pet Therapy Work?

The therapeutic uses of pet therapy are well-researched. Interacting with animals has been proven to help people suffering from physical and/or mental health disorders cope and recover better.

Playing or stroking animals, or even watching them can lower the levels of cortisol and increase the production of serotonin, making us less stressed and happier. Pet therapy for depression treatment and addressing trauma, social anxiety and isolation, and chronic self-harm are in practice.

Types Of Pet Therapies

The primary 4 types of pet therapy include:

1. Therapeutic Visitation

In this type of pet therapy, household pet owners take their pets to visit healthcare facilities on a voluntary basis. The animals often help hospitalized patients feel happier and more hopeful, pushing them toward faster recovery.

2. Animal-assisted Therapy

In this therapy, animals are specifically trained 4 to assist therapists with their patients. As opposed to therapeutic visitations, in this type of therapy a trained animal-assisted therapist includes a specific animal as part of their weekly therapy sessions.

3. Facility therapy

In this type of pet therapy, therapy animals are trained and made to reside in care centers. They engage with visiting patients who are battling serious mental disorders like PTSD, dementia, etc.

Benefits Of Pet Therapy

Studies on human-animal interactions are very few indicating the need for more research in this area. Existing studies showed how a pet can help with mental health and positive physical health effects, but the results have been mixed.

The common 5 pet therapy benefits are:

  1. Improved patient satisfaction
  2. Enhanced energy levels
  3. Greater self-esteem
  4. Boost in moods
  5. Decreased loneliness and depressive symptoms
  6. Increased motor skills
  7. Improved social skills and verbal communication
  8. Decreased boredom
  9. Development of a positive outlook on life

In people with hypertension, particularly the elderly population 6, petting animals lower blood pressure, cholesterol levels, and triglyceride levels. This also decreases the risks of cardiac diseases (like stroke and heart failure).

The benefits of pet therapy for seniors also include increased opportunities for exercise as well as socializing and outdoor activities. This, in turn, helps them achieve better cognitive function—thereby reducing their vulnerability to cognitive impairment and memory disorders (such as dementia).

Risks Of Pet Therapy

Some of pet therapy’s biggest risks 7 are with regard to safety and sanitization. People who are allergic to animal dander or have a pathological fear of animals may especially experience negative reactions.

They are at a risk of being exposed to zoonotic pathogens—that too directly in a hospital environment 8—through petting, licking, or contaminated food. The therapy animals can also spread these pathogens from visitors to patients and caregivers or vice versa.

There is also a chance of injuries, such as a fall or bites and scratches. However, in most cases, animals in pet therapy programs are typically screened for behavior and health.


The effectiveness of pet therapy is confirmed by recent research and it is considered a successful non-pharmacological intervention (with little to no side effects) for physical and mental health conditions. It is a viable ancillary therapy especially for people who are fond of animals.
