Animal-Assisted Therapy (AAT)

Reviewed by the HeyPsych Medical Review Board

Board-certified psychiatrists and mental health professionals

Published September 2, 2026•Updated September 2, 2026•Reviewed September 2, 2026

Indications

Primary Indications

Mood disorders (anxiety, depression)PTSD and trauma recoveryAutism spectrum and developmental disordersRehabilitation support (physical, occupational, speech)Dementia-related agitation

Mechanism

AAT leverages the human–animal bond, which modulates stress physiology by lowering cortisol, enhancing oxytocin release, and improving heart rate variability. Interacting with animals provides sensory stimulation, fosters social connection, and facilitates emotional expression. Structured activities enhance engagement, motivation, and adherence to therapeutic tasks, while physical interaction (e.g., grooming, walking) can support motor rehabilitation.

Protocol

Preparation

Clinical assessment of goals, patient suitability, and potential contraindications; informed consent; pairing with appropriate therapy animal.

Procedure

  1. Structured activities with therapy animals tailored to patient goals (e.g., grooming horses for trauma therapy, playing fetch for social engagement, walking dogs for mobility training).
  2. Facilitated processing by therapist linking experience to therapeutic objectives.
  3. Monitoring for safety, stress, or adverse reactions in both patient and animal.

Frequency: Weekly or biweekly sessions depending on clinical goals.

Duration: 30–60 minutes per session.

Total Treatment Time: 6–12 sessions for initial course; ongoing as indicated.
