Pet therapy fits into a person-centered dementia care plan as one optional activity choice, written into the plan only if it matches a specific resident's own history, preferences, and remaining abilities. Person-centered dementia care, as defined by the Alzheimer's Association, means building support around the individual rather than a facility's routine, so a dog or cat visit belongs on the plan only for someone who has shown an affinity for animals.
That framing matters because the research on animal-assisted therapy for dementia is mixed. It can support a person's sense of identity during a visit, but it has not been shown to reliably change cognition, agitation, or daily functioning. The sections below explain what the evidence does and does not support, how pet therapy should be documented in a care plan, and what safety steps a facility needs before a visit happens.

What Person-Centered Care Actually Requires
Person-centered dementia care is a specific framework, not a general philosophy of kindness. The Alzheimer's Association defines it as care built around a person's history, preferences, and remaining abilities, rather than around staff schedules — and it extends to supporting the people caring for them, including family caregivers. An Alzheimer's Disease International member survey, reported in a peer-reviewed study, narrowed this into five tenets: individualized care, valuing the person, empowering the person, respecting caregivers, and addressing wellness.
Any activity added to a care plan, including a pet visit, has to serve at least one of these five goals for a specific person — not function as a scheduled group activity offered to everyone regardless of fit. In US nursing homes, this isn't just a best practice; it's a regulatory requirement. Federal regulation 42 CFR 483.21(b)(1), CMS tag F656, requires that each resident's comprehensive care plan be person-centered, with measurable objectives drawn from the facility's own assessment of that resident's medical, nursing, and psychosocial needs. Pet therapy, when it appears in a plan, has to be tied to one of those objectives — for example, reducing a documented pattern of agitation or supporting social engagement for a resident who has shown interest in animals.
What the Research Actually Shows About Pet Therapy's Effects
The evidence behind animal-assisted therapy for dementia is thinner than its popularity suggests. A 2019 Cochrane review found only two trials with 83 total participants measuring depression, and judged the evidence low-certainty even for that modest finding of possible benefit. The same review found no clear effect on agitation, social functioning, or activities of daily living, and noted that none of the included studies reported on adverse events. A larger analysis pooling 19 randomized controlled trials, published in a 2023 network meta-analysis, reached a similar conclusion: pet-robot therapy produced a marginal benefit for agitation compared to no intervention, but neither live animal-assisted therapy nor pet-robot therapy improved cognition, depression, or quality of life.
Smaller studies add nuance without overturning this picture. A matched-pair controlled trial of 54 nursing-home residents, described in a case-control study, found that ten weekly animal-assisted-therapy sessions kept one group's agitation stable while a usual-care-only comparison group's agitation worsened — though neither group showed overall improvement. A Dresden pilot study covered by Nature Index compared a therapy dog with a handler against the same handler alone, and found both conditions appeared to improve psychosocial wellbeing — meaning the dog didn't clearly outperform simple human social contact. Taken together, this means a care team should not add pet therapy to a plan expecting it to reliably lower agitation, lift mood, or slow cognitive decline. The evidence doesn't support that as a dependable outcome.
Where Pet Therapy Earns Its Place — Identity and Dignity
If pet therapy isn't a proven treatment for dementia symptoms, what does it actually offer? The clearest answer comes from how it affects a person's sense of self during the time they spend with an animal. A phenomenological study of older adults with Alzheimer's disease, published in a qualitative research article, found that participants drew on their own remaining abilities while interacting with a therapy dog and could temporarily set their symptoms aside — described as being able to "be themselves" again. That outcome maps directly onto person-centered care's core goals: valuing the person and empowering them, as named in the five-tenet framework.
A resident who spent years with dogs, or who worked on a farm, may recover a piece of identity during a supervised visit that no symptom-tracking chart will capture. This is the strongest, most specific justification for writing pet therapy into an individual plan — not as symptom management, but as an activity matched to who that person has always been. This is also why pet therapy cannot be a blanket activity. A resident with no history or interest in animals gains none of this identity benefit, and a resident with a fear of dogs could be distressed by the same visit that helps someone else.
Safety Steps Before Any Visit Happens
Any facility introducing pet therapy needs infection-control measures in place first. The CDC's guidance on animals in health-care facilities calls for strict hand hygiene after every contact with a therapy animal, discourages animals under one year old because their behavior is less predictable, and requires that visits be supervised by a handler specifically trained with that individual animal. Despite this guidance existing, practice varies widely across facilities.
A CDC-published 2023 survey, reported by the CDC, of 104 US infectious-disease specialists found that 88% worked at facilities that permit animal-assisted activities or pet visitation, but policies differed widely on which species were allowed, which areas were off-limits, and whether animals received veterinary screening. The same survey called for standardized infection-prevention protocols precisely because this inconsistency exists. Families considering a facility for a loved one can reasonably ask what that specific facility's animal-visit policy covers before assuming any version of "pet therapy" meets the same safety bar.
- Confirm the handler is trained with the specific animal visiting, not just animals in general
- Require hand hygiene for the resident and staff immediately after contact
- Avoid animals under one year old
- Screen residents for allergies, open wounds, or compromised immune systems before scheduling a visit
Getting Pet Therapy Written Into a Care Plan
Because US nursing-home care plans must be person-centered under federal regulation, adding pet therapy isn't a matter of signing up for a weekly activity — it goes through the resident's individual assessment and plan review. A family member or care partner who brings a documented personal history with animals to that conversation gives the care team the specific detail a person-centered plan requires — the detail that turns pet therapy from a generic activity into one aimed at a particular person.
- Raise the resident's personal history with animals during a care-plan meeting — not as a general suggestion, but tied to a specific pet, farm, or work history if one exists
- Ask the facility how it documents outcomes from the visits it already offers, so the plan includes a measurable objective rather than just scheduling a visit
- Confirm the facility's handler-training and infection-control practices match the CDC's standards before the first visit
- Expect the visit to support mood or identity in the moment rather than produce a lasting change in agitation or cognition, given what the Cochrane review and network meta-analysis found
- Revisit the plan if the resident shows distress rather than engagement, since a visit that helps one person can unsettle another
Frequently Asked Questions
Does pet therapy improve memory or slow dementia progression?
No. The 2023 network meta-analysis found neither animal-assisted therapy nor pet-robot therapy improved cognition in people with dementia.
Is a real animal better than a robotic one for dementia care?
The evidence doesn't show a clear advantage either way. The same network meta-analysis found pet-robot therapy gave a marginal benefit for agitation, while live animal-assisted therapy showed no clear effect on it.
Who decides whether pet therapy goes into a resident's care plan?
In US nursing homes, it's addressed through the resident's comprehensive care-plan process required under 42 CFR 483.21(b)(1), based on the facility's individual assessment of that resident.
