Before starting pet therapy for a loved one with dementia, ask about the evidence behind it, the type of animal or robot used, the facility's health and safety protocols, and who is responsible for the animal's day-to-day care. Pet therapy, also called animal-assisted therapy or animal-assisted intervention, uses structured contact with a live animal or a lifelike robotic pet to ease dementia symptoms such as agitation and low mood. The answers to these questions determine whether a program is likely to help, whether it's safe for a resident with a weakened immune system or mobility limits, and whether the facility has planned for the animal's welfare as carefully as the resident's. Asking them before the first visit avoids disappointment and prevents avoidable health risks.

What does the research actually show?
A 2023 systematic review pooled 51 studies on animal-assisted interventions for dementia and found reductions in agitation, though the review noted that only a small number of randomized controlled trials fed into that pooled estimate. That distinction matters: the review combined 18 RCTs with 12 non-randomized trials, 13 cohort studies, and 7 qualitative studies, so the agitation finding rests on a mix of stronger and weaker evidence. A separate meta-analysis of nine randomized controlled trials, covering both live animals and robotic pets, found a statistically significant reduction in depression among people with dementia.
That meta-analysis also reported that effects on agitation and quality of life were inconsistent across the included trials. A retrospective study of 127 people with mild-to-moderate Alzheimer's disease in southern Italy found that adding animal-assisted therapy to standard reality-orientation therapy improved cognition and depression scores more than reality-orientation therapy alone, according to the study. The design wasn't randomized, so ask any program whether its claims are based on controlled trials or observational results like these before expecting a specific outcome.
Does it matter whether the animal is real or robotic?
Yes. A Griffith University-led randomized trial compared the PARO robotic seal, a plain plush toy, and usual care in dementia residents. The trial found that PARO modestly but significantly increased pleasure and reduced agitated behavior compared with usual care, but a plush toy with no robotics matched PARO's effect on reducing neutral affect.
A 12-week randomized trial of PARO sessions with 61 elderly dementia patients found decreased stress and anxiety in the treatment group, along with a drop in psychoactive- and pain-medication use compared with controls, according to the trial published in the Journal of Alzheimer's Disease. Ask whether a program has measured outcomes specific to the animal or robot it uses, rather than assuming results from one type of intervention apply to another. A robotic pet also sidesteps live-animal concerns like allergies, bites, and infection control, which makes it a reasonable first question for a resident with a compromised immune system or a known fear of animals.
What health and safety protocols should the facility have in place?
Ask whether the facility follows infection-control guidance for therapy animals before agreeing to a visit. Long-term-care guidance from the Utah Department of Health and Human Services directs facilities to keep therapy animals out of rooms under transmission-based precautions, never leave an animal unsupervised with a resident, confirm current veterinary clearance and vaccination, and require hand hygiene before and after contact, according to the guidance. Ask what the animal eats during visits and who verifies its health records.
A survey of 45 eldercare facilities, 45 hospitals, and 27 therapy-animal organizations found that 70% of therapy-animal organizations allowed animals to eat raw meat or treats, a recognized source of bacterial contamination, and 22% of eldercare facilities had no formal animal-visitation policy at all, according to the survey summary. A facility with no written policy has no standard to hold the program to. A systematic review of eight randomized controlled trials on animal-assisted therapy in dementia populations also flagged possible adverse events to the therapy animals themselves, animal-welfare concerns, and program cost as practical barriers, according to the review. Ask how the program screens for animal fatigue or stress, not just resident safety.
Who supervises each visit, and who is responsible for a resident's own pet?
Ask who supervises the animal during every single visit, not just during intake. A facility-evaluation checklist for animal-assisted programs recommends confirming this directly, along with whether a specific resident has a documented allergy or fear of animals, according to the checklist. Ask the same checklist's third question if the resident still lives with a pet of their own: who takes responsibility for that pet if advancing dementia makes self-care impossible.
This is a separate issue from facility-based therapy visits, but families often face both at once, and a plan should exist before a crisis forces one. Confirm, too, that any known allergy or fear is recorded somewhere the visiting handler will actually see it, not just in a general intake file. A program that cannot answer who checks this before each visit has not finished building its safety process.
What should a family ask before saying yes?
Use this short list as a starting point when evaluating a specific program: A program that can answer all five with specifics, rather than general reassurance, has done the planning that the research and safety guidance above call for.
- Is the claimed benefit (agitation, depression, pleasure) backed by a randomized trial, or by observational data alone?
- Does the program use a live animal, a robotic pet like PARO, or both, and why that choice for this resident?
- What is the facility's written infection-control policy, including animal diet and veterinary clearance?
- Who supervises the animal during visits, and is the resident's allergy or fear status documented?
- What happens to a resident's own pet if they can no longer care for it themselves?
