What Is Animal-Assisted Therapy?
Animal-assisted therapy (AAT) is a structured, goal-directed therapeutic intervention in which a trained animal is incorporated into a patient’s treatment plan. Unlike casual pet visits, AAT is facilitated by a licensed healthcare professional — such as a psychologist, occupational therapist, or physical therapist — who uses the animal as a clinical tool to achieve specific treatment objectives.
AAT is recognized by the American Psychological Association and is used in hospitals, rehabilitation centers, mental health clinics, schools, and veteran care programs across the United States.
How Does Animal-Assisted Therapy Work?
The therapeutic mechanism behind AAT operates on multiple levels:
- Physiological: Interacting with animals triggers the release of oxytocin, serotonin, and dopamine while reducing cortisol levels. Blood pressure and heart rate decrease measurably during animal-assisted sessions.
- Psychological: Animals provide non-judgmental interaction, which reduces social anxiety and creates a safe emotional space. This is especially valuable for trauma survivors and individuals with PTSD.
- Social: Animals serve as social catalysts, encouraging verbal communication in children with autism, patients with aphasia, or individuals who are withdrawn or isolated.
- Physical: Activities like brushing, walking, or playing with a therapy animal improve fine motor skills, range of motion, and cardiovascular fitness.
Types of Animal-Assisted Therapy Programs
Animal-Assisted Therapy (AAT)
Formal therapeutic sessions directed by a licensed clinician with specific treatment goals. Progress is documented and measured. Examples: a psychologist using equine therapy for PTSD treatment, or an OT using a dog to motivate a stroke patient’s hand rehabilitation.
Animal-Assisted Activities (AAA)
Less formal, feel-good interactions designed to improve general well-being. Therapy dog visits to nursing homes and hospital wards are the most common form. No formal treatment plan is required.
Animal-Assisted Education (AAE)
Programs that incorporate animals into educational settings. Reading therapy dogs (where children read aloud to a calm dog) have demonstrated measurable improvements in reading fluency and confidence.
Equine-Assisted Therapy (Hippotherapy)
Uses the rhythmic movement of horseback riding to improve posture, balance, coordination, and core strength. Widely used for children with cerebral palsy, autism spectrum disorder, and developmental delays.
Which Animals Are Used in Animal-Assisted Therapy?
| Animal | Best For | Setting |
|---|---|---|
| Dogs | Anxiety, PTSD, social skills, rehabilitation | Hospitals, clinics, schools, disaster relief |
| Horses | Physical rehabilitation, autism, PTSD | Equestrian centers, veteran programs |
| Cats | Elderly companionship, stress reduction | Nursing homes, assisted living |
| Rabbits | Child therapy, sensory processing | Pediatric clinics, schools |
| Dolphins | Autism, cerebral palsy, depression | Marine facilities (limited availability) |
| Birds | Cognitive stimulation, elderly engagement | Nursing homes, psychiatric facilities |
Benefits of Animal-Assisted Therapy
Mental Health Benefits
- Reduces symptoms of anxiety and depression
- Decreases feelings of isolation and loneliness
- Improves self-esteem and emotional regulation
- Helps process trauma (especially in PTSD patients)
- Increases motivation and treatment compliance
Physical Health Benefits
- Lowers blood pressure and heart rate
- Improves fine and gross motor skills
- Enhances mobility and balance (especially equine therapy)
- Reduces perception of pain during rehabilitation
Social and Cognitive Benefits
- Encourages verbal and non-verbal communication
- Improves social interaction skills in children with autism
- Stimulates memory and cognitive function in dementia patients
- Builds empathy and responsibility
Who Can Benefit from Animal-Assisted Therapy?
AAT programs have shown measurable results for:
- Veterans with PTSD — Equine and canine therapy reduce hypervigilance and improve emotional regulation.
- Children with autism — Animal interactions improve social engagement and reduce sensory overload.
- Stroke patients — Motivation to interact with a therapy dog increases participation in physical rehabilitation.
- Hospice patients — Animal visits provide comfort and reduce end-of-life anxiety.
- Individuals with depression and anxiety — Regular animal-assisted sessions can complement medication and talk therapy.
If you personally benefit from the calming presence of an animal for a mental health condition, you may qualify for an emotional support animal (ESA). An ESA provides you with legal housing protections under the Fair Housing Act.
How to Find Animal-Assisted Therapy Near You
- Ask your healthcare provider — Many therapists, psychiatrists, and rehabilitation centers offer or can refer you to AAT programs.
- Contact Pet Partners — The largest therapy animal organization in the U.S. maintains a directory of registered therapy animal teams.
- Search hospital programs — Major hospitals often have established volunteer therapy dog programs.
- Look for equine therapy centers — The Professional Association of Therapeutic Horsemanship (PATH) International certifies equine therapy centers nationwide.
Animal-Assisted Therapy vs. Emotional Support Animals
AAT and ESAs are fundamentally different:
- AAT is a professional clinical intervention administered by a therapist. The animal belongs to the therapist or a volunteer handler.
- An ESA is your own pet that provides ongoing emotional support for your diagnosed mental health condition. ESAs are protected under the Fair Housing Act for housing accommodations.

Frequently Asked Questions
Is animal-assisted therapy covered by insurance?
When AAT is part of a formal treatment plan administered by a licensed clinician, some insurance plans cover it as part of occupational therapy, physical therapy, or psychotherapy. Check with your provider.
How is animal-assisted therapy different from pet therapy?
“Pet therapy” is a casual term often used for animal-assisted activities (informal comfort visits). True animal-assisted therapy is a structured clinical intervention with measurable treatment goals.
Can any animal be a therapy animal?
Therapy animals must be temperament-tested, obedience-trained, and registered with a recognized organization. Dogs are the most common, but cats, rabbits, horses, and other species can also serve in therapy roles.
How long does an animal-assisted therapy session last?
Formal AAT sessions typically last 30–60 minutes, similar to standard therapy appointments. Animal-assisted activity visits (e.g., hospital ward visits) may last 15–45 minutes.
