Pet therapy can be safe for people with dementia when specific precautions are in place, but safety does not happen automatically. The risks are real and measurable: falls during interaction, infections from animal contact, bites or scratches, and behavioral escalation in individuals who become agitated or afraid. A 72-year-old man with moderate Alzheimer’s disease attended a weekly pet therapy visit where handlers brought a calm, certified therapy dog into the memory care unit. During the visit, he stood to pet the dog, lost his balance, and fell—breaking his hip.
The dog had done nothing wrong; the environment had not been prepared for his specific gait and mobility limitations. The difference between a safe program and an unsafe one is preparation. This means screening animals before they enter a dementia care setting, training both the person with dementia and staff on proper interaction, modifying the physical space to prevent falls, and maintaining clear supervision at all times. Pet therapy does provide documented benefits for people with dementia—reduced agitation, lower blood pressure, increased social engagement. But these benefits only outweigh the risks when safety protocols are actually followed, not when they’re listed on a brochure and ignored in practice.

What Are the Main Safety Risks of Pet Therapy for Dementia Patients?
The primary physical hazard is falls. people in the middle to later stages of dementia often have gait disturbances, poor balance, or reduced awareness of their surroundings. When a pet approaches—especially a large dog—the person may try to stand to interact, may lean forward to pet the animal, or may become distracted and miss obstacles or uneven flooring. They may also forget that the animal is present and trip over it. A 68-year-old woman with vascular dementia attended a pet therapy session where the dog jumped up excitedly. She stepped backward to create distance and fell over a chair that had not been moved to the side. Bites and scratches are less common than falls but far more serious when they occur.
A person with dementia may not interpret a dog’s warning signs—stiffened posture, growling, ears pinned back—as a signal to back away. They may also grab or squeeze an animal, pull its tail, or poke it, which triggers defensive reactions even in a normally gentle dog. Cats pose a lower risk of severe bites but can cause scratches that become infected in people with fragile skin or compromised immune systems. Allergic reactions and infections form a third category. Direct contact with animal fur can trigger respiratory or skin allergies. Less obviously, infections—including MRSA, ringworm, and parasites—can transfer from animals to people, particularly those whose immune systems are weakened by age or illness. A resident in a memory care community contracted ringworm from a therapy cat, and the infection spread to three other residents before it was identified and treated.
How Do Behavioral Challenges Affect Safety in Pet Therapy?
Some people with dementia become frightened by animals they would have loved before their illness. This fear may stem from loss of memory, misidentification (seeing the pet as a threat or a different object), or changes in sensory perception. When frightened, they may strike out, try to run away, or become severely agitated. A man with late-stage Alzheimer’s saw a rabbit in a therapy session and became convinced it was a rat invading his space; he fought with staff members and had to be removed to another room, experiencing several hours of heightened distress afterward. The opposite reaction—overstimulation and inappropriate interaction—is equally common.
Some people with dementia become overly excited by animals, lose impulse control, and pet too roughly, hold the animal too long, or try to pick it up. They may not respond to redirects from staff. One woman with frontotemporal dementia repeatedly grabbed at a visiting dog’s face during therapy sessions, despite consistent intervention, and the program had to be discontinued because the dog became defensive. A limitation of pet therapy programs is that no screening tool perfectly predicts which individuals will respond safely and which will not. A person who was calm during an initial visit may become agitated or frightened during a follow-up session. Families sometimes report that their loved one “was always an animal person” and assume therapy will go smoothly, but dementia changes how the brain processes and responds to stimuli, and past preferences are not reliable guides.
What Does Proper Animal Screening Look Like?
A screening program should evaluate the animal’s baseline temperament, training, behavior under stress, and tolerance for unexpected contact—especially handling by hands that may be unpredictable. Certified therapy animals have undergone formal temperament testing and training, usually through organizations like Delta Society or the American Kennel Club’s Therapy Dog program. These certifications require documented proof that the animal remained calm when handled roughly, startled by loud noises, or approached by people moving in unexpected ways. Even certified animals may not be suitable for all dementia settings. A large, energetic dog certified for therapy might be perfectly safe with ambulatory older adults but dangerous around wheelchair users who could be knocked over. A cat certified for calm, controlled environments might become stressed by the noise and chaos of a busy memory care unit, increasing the risk it will bite or scratch.
Staff must evaluate not just the animal’s general suitability but its fit for the specific population and setting. Un-certified or home-trained animals should not be used in organized dementia care programs. The legal liability is substantial, and the risk to residents is high. A memory care community once allowed a staff member to bring her personal dog, described as “really friendly,” to visit a resident. The dog was not certified and had no formal behavioral assessment. During the visit, it bit another resident who approached it, resulting in a lawsuit and the community’s reversal of its pet therapy policy.
How Should the Physical Environment Be Prepared?
The space where pet therapy occurs should be cleared of hazards that a person with dementia might encounter while their attention is on the animal. This includes removing chairs and tables that could cause trips, ensuring flooring is not slippery or uneven, and eliminating cords or loose items the person could catch their foot on. Adequate lighting is essential because many people with dementia have visual impairment, and poor lighting combined with divided attention increases fall risk substantially. Staff must remain positioned to physically support the person if they lose balance. This is not passive monitoring; it requires active readiness.
One facility trained staff to stand within arm’s reach of the person during animal interaction, ready to provide steadying contact. Another facility positioned staff nearby but not close enough to intervene quickly; a resident lost balance twice during one session before staff recognized the need for closer proximity. The environment should also control the animal’s movement. The animal should not be free to jump, climb on furniture, or move unpredictably through the space. Using a gate or enclosed area keeps the animal in a defined zone and prevents it from approaching residents who might not tolerate interaction. Seating should be provided so the person with dementia can remain seated during most or all interaction, reducing fall risk and allowing for more controlled, safer contact.
What Infection Control Measures Are Necessary?
Hand hygiene before and after animal contact is non-negotiable. Staff should ensure that people with dementia wash or have their hands cleaned after touching an animal. This is complicated by the fact that many individuals with dementia will resist being told to wash their hands or may not remember why they’re being asked to do so. A practical approach used in some care facilities is to make hand-washing part of a natural routine—immediately after the pet visit, offer a hand wash or wipe before a snack or beverage, framing it as part of the activity rather than a safety requirement. Staff should also monitor for any breaks in the person’s skin. Minor cuts, abrasions, eczema, or other skin conditions increase infection risk from animal contact.
Individuals on immunosuppressive medications, with diabetes, or with chronic kidney disease face higher infection risk and may need more rigorous infection control or longer intervals between animal contact. Animals used in dementia settings must be current on vaccinations, including rabies, and should be screened for common transmissible conditions like ringworm before beginning visits. Some facilities require a veterinary health certificate annually. However, a significant limitation is that animals can acquire new infections between visits. A therapy dog certified and cleared three months ago may have picked up a zoonotic illness in the interim. Ongoing assessment by the facility, not just reliance on initial clearance, is necessary.
How Should Interactions Be Guided and Limited?
Staff should teach basic safe interaction—petting the dog on its back or side, not grabbing its face or ears, not pulling the tail. For people with moderate to late-stage dementia, these instructions may not be retained or understood. In these cases, staff must actively direct and redirect the person’s hands throughout the interaction. Some facilities use guided-hand techniques where staff place their hand over the person’s hand, guiding it to pet the animal gently, then release and observe whether the person continues appropriately or needs redirection.
Session length matters. A 30-minute visit can overstimulate someone with dementia, leading to agitation or behavioral escalation that lasts hours after the animal leaves. Shorter, more frequent visits—10 to 15 minutes—often produce better outcomes with fewer behavioral risks. One memory care community experimented with 45-minute pet therapy sessions and found that residents became increasingly agitated as the session progressed, despite the animal’s calm behavior.
When Should Pet Therapy Be Avoided or Discontinued?
Pet therapy is not appropriate for everyone with dementia. Those with severe fear responses to animals, individuals with advanced illness who become overstimulated easily, and those with documented aggressive behaviors should be excluded from programs or should participate only under extremely close supervision. Additionally, people with severe allergies, open wounds, or active infections should not participate in animal contact.
Discontinuation should happen immediately if an animal shows signs of stress or aggression, if a person with dementia shows sustained fear or behavioral escalation, or if any injury or infection occurs. A facility should document each session, noting any concerning behaviors, near-misses, or medical issues, so that patterns emerge and problems can be addressed before they result in harm. One community kept no records of its pet therapy program for a year, then discovered in hindsight that the same three residents had fallen during or shortly after animal visits—a pattern that should have triggered protocol changes much earlier.

Frequently Asked Questions
Is it safe for someone with dementia to have a pet at home?
Home pets present different risks than therapy animals. Responsibility for care often shifts entirely to caregivers. Safety depends on the animal’s temperament, the person’s mobility and behavioral state, and the caregiver’s ability to manage both the person and the animal simultaneously. Some families find it works well; others discontinue the pet after a fall or behavioral incident.
Can pet therapy worsen dementia-related aggression?
Yes, if the person becomes overstimulated or frightened by the animal. Conversely, interaction with a calm, appropriate animal can reduce aggression in some individuals. The outcome depends on the specific person, the animal, and how the session is managed.
What should I do if my loved one is afraid of the therapy animal?
Inform staff immediately. Do not force or encourage interaction. Fear can intensify behavioral symptoms and anxiety for hours afterward. If fear persists across multiple sessions, discontinue the program.
Are there animals safer than dogs for people with dementia?
Cats, rabbits, and fish can be gentler options for some individuals, but they are not universally safer. Cats can scratch; rabbits can bite or injure if held incorrectly; fish offer interaction but no tactile contact. The best animal is the one suited to the individual person.
Who should supervise pet therapy sessions?
Staff trained in both dementia care and animal behavior should supervise. The handler who brings the animal alone is not sufficient; facility staff must be present to monitor the person with dementia for safety, behavioral changes, and appropriate interaction.
What liability does a facility have if someone is injured during pet therapy?
Facilities can be held liable for injuries during pet therapy if they failed to screen the animal, prepare the environment, or provide adequate supervision. Liability waivers do not eliminate this responsibility. Proper documentation of screening, training, and incident-free sessions protects the facility legally and, more importantly, protects residents. —
