Pet Therapy for Chronic Pain: Benefits, Evidence, and Practical Steps

Pet therapy for chronic pain is the use of animals to provide comfort, social support, and structured therapeutic activities for people living with long-term pain conditions. Research and clinical practice increasingly consider animal-assisted interventions as one component within a biopsychosocial approach to pain management.

Pet therapy for chronic pain: an overview

Animal-assisted therapy (AAT) and related supports use interactions with trained animals—often dogs, cats, or other companion animals—to address emotional, social, and sometimes physical goals. For people with chronic pain conditions such as osteoarthritis, fibromyalgia, or persistent post-surgical pain, these interactions may help by reducing perceived pain intensity, lowering stress hormones, and improving mood or sleep.

How pets may help people with chronic pain

Psychological and social effects

Contact with animals can provide comfort, reduce feelings of isolation, and increase social engagement. Studies have shown short-term reductions in anxiety and depressive symptoms following guided sessions with therapy animals. Social support is a recognized factor in quality of life and coping with chronic illness.

Physiological pathways

Interactions with animals are associated with measurable physiological changes in some studies, including lower cortisol (a stress hormone), increases in oxytocin (linked to bonding), and modest reductions in heart rate and blood pressure. These responses may indirectly influence pain perception through stress reduction and improved mood.

Activity and functional benefits

Companion animals can encourage light physical activity—walking a dog or gentle play—which helps maintain mobility, circulation, and daily routine. For some people, increased activity and structure support pacing strategies and can reduce the long-term effects of deconditioning.

What the research and guidelines say

Evidence for animal-assisted interventions spans randomized controlled trials, cohort studies, and qualitative reports. Systematic reviews often characterize the evidence as promising but heterogeneous: study sizes, methods, and outcome measures vary. Major health organizations recognize psychosocial supports as part of chronic pain management, while also calling for more rigorous trials on pet-based interventions.

For context on chronic pain as a clinical topic, see information from the National Institutes of Health (NIH/NINDS), which summarizes causes, prevalence, and recommended multidisciplinary treatment approaches.

Types of animal-assisted programs and who runs them

Professional animal-assisted therapy (AAT)

AAT is delivered by trained health professionals working with animals handled by trained handlers. Goals are individualized and documented as part of a treatment plan. Programs often follow standards from professional bodies in healthcare and animal welfare.

Facility-based and volunteer visits

Visits by volunteer therapy animal teams to hospitals, clinics, or group settings focus on comfort and engagement rather than formal therapy goals. These interactions are typically shorter and may be organized by community groups or healthcare facilities.

Companion animals and service/support animals

Some people adopt or live with companion pets that provide ongoing emotional support. Service animals have specific trained tasks (e.g., mobility assistance) and legal protections. Emotional support animals differ by jurisdiction and are not the same as trained service animals.

Safety, ethics, and practical considerations

Health and infection control

Programs should follow infection control guidance, particularly in healthcare settings, to reduce risks for people with compromised immune systems. Veterinary oversight and routine animal health checks are important.

Animal welfare and training

Therapy animals should be evaluated for temperament and receive training appropriate to their role. Animal welfare organizations and veterinary associations provide guidelines on humane treatment and safe working conditions for animals.

Suitability and consent

Not everyone will benefit from or want interactions with animals. Allergies, fear of animals, cultural preferences, and individual clinical circumstances should guide whether pet-based approaches are offered. In clinical programs, informed consent and person-centered goals are standard practice.

How to explore pet therapy safely

When considering pet therapy for chronic pain, discuss options with a healthcare provider or pain management team. Confirm that any program follows local regulations, has trained personnel, and uses animals that are healthy and temperament-tested. Community-based organizations, certified therapy animal groups, and licensed healthcare providers can help identify appropriate programs.

Cost and access

Access varies by region. Some volunteer programs provide free visits; professional AAT may be offered through clinics and could be covered by some health plans or research programs. Check local resources and disability services for support with access.

Measuring outcomes

Programs often track mood, pain ratings, activity levels, or functional goals. Reliable measurement helps determine whether the intervention meets individual needs and supports adjustments over time.
