For millions of Canadian households, pets aren’t just animals — they’re family. They also happen to be genuinely good for us: pet ownership has been linked to lower blood pressure, reduced feelings of isolation, and improved mental wellbeing, especially for seniors living alone. But it’s also fair to ask the question a lot of people quietly wonder about: can the family dog, cat, or bird actually make you sick?
The honest answer is yes, sometimes — but the risk is small, well understood, and easy to manage with a few consistent habits. Here’s what’s actually worth knowing.
How Pets Can Make Us Sick: Understanding the Basics
Diseases that pass from animals to humans are called zoonotic diseases, and they’re more common than most people realize — though usually mild. Pets can carry bacteria, parasites, or fungi on their fur, in their saliva, or in their waste that, under the right circumstances, can be transmitted to the people who care for them. This doesn’t mean every pet is a health hazard. It means hygiene and awareness matter, the same way they do with food safety or handwashing.
Common Health Risks From Household Pets
- Bacterial infections, such as salmonella or campylobacter, most often linked to reptiles, birds, and occasionally contaminated pet food or treats.
- Parasites, including roundworms, hookworms, fleas, and ticks. Ticks in particular carry the added risk of Lyme disease, which has been expanding into more parts of Canada in recent years.
- Ringworm, a fungal skin infection that’s easily passed between pets and people through direct contact.
- Toxoplasmosis, associated with cat feces, which poses a specific risk to pregnant women and people with weakened immune systems.
- Cat scratch disease, a bacterial infection that can develop from a scratch or bite that isn’t properly cleaned.
- Pet allergies and asthma, triggered by dander, saliva, or shed fur — often the most common “illness” pets cause, even without any infection involved.
Most of these risks are avoidable with basic precautions, and healthy adults with intact immune systems face a fairly low overall risk from typical, well-cared-for household pets.
Who’s Most at Risk
Certain groups need to be a little more cautious around pets, not because pets are dangerous, but because their bodies are less able to fight off infections that a healthy adult would shrug off easily. This includes young children, pregnant women, and people with weakened immune systems from illness or medication.
It’s also worth extra attention for older adults and anyone managing a chronic wound, recovering from surgery, or using home medical equipment. Reduced circulation, slower wound healing, and skin that’s more easily broken down all raise the stakes if a scratch, bite, or contaminated surface introduces bacteria. This is especially relevant in home care settings, where pets, mobility equipment, and wound care routines often share the same living space.
Simple Habits That Keep Everyone Safe
- Wash your hands after handling pets, cleaning litter boxes, or cleaning up after an accident — this single habit prevents the majority of pet-related illness.
- Keep vaccinations and parasite prevention current, including flea, tick, and deworming treatments recommended by your veterinarian.
- Clean bites and scratches promptly with soap and water, and monitor for redness, swelling, or warmth over the following days.
- Avoid letting pets near open wounds, catheters, or medical equipment, particularly for anyone managing a healing wound or using home care devices.
- Keep litter boxes away from food preparation areas, and have someone other than a pregnant household member handle litter box cleaning when possible.
Special Considerations for Home Care and Caregiving Households
If your household includes both pets and medical equipment — a hospital bed, wheelchair, or mobility aid — a bit of extra attention to surface hygiene goes a long way. Pet hair and dander can accumulate on upholstery and cushioning, and porous surfaces are harder to keep genuinely clean over time.
This is one of the reasons washable, infection-control-rated surfaces have become standard in home care equipment. Our wheelchair cushion selection and pressure relief guide covers gel and cover options that are specifically designed to be wiped down or machine-washed, which matters more than people expect in households with pets. You can also browse our full range of infection-control-friendly products if you’re looking to make a home care setup easier to keep clean.
For families supporting a loved one through daily caregiving — transfers, positioning, and general home care — our guide to patient handling and transfer solutions is worth a look, since good equipment hygiene habits tend to matter most in exactly these households.
The Other Side: Why Pets Are Still Worth It
None of this is meant to talk anyone out of pet ownership. For many seniors, a pet provides genuine companionship, a reason to stay active, and a meaningful buffer against social isolation — which carries its own well-documented health risks. The goal isn’t to avoid pets; it’s to enjoy them with a bit of awareness, especially in households where someone is managing a chronic condition, recovering from illness, or using home medical equipment.
When to See a Doctor
Most pet-related health concerns are minor and resolve on their own with basic care. But it’s worth seeing a doctor if a bite or scratch shows signs of infection, if a rash or skin irritation doesn’t improve after a few days, or if anyone in the household — especially someone immunocompromised — develops an unexplained fever after contact with a pet or its waste.
The Bottom Line
Pets bring real, measurable benefits to physical and mental health, and for most people, the risk of illness from a well-cared-for household pet is genuinely low. A little consistent hygiene — handwashing, prompt wound care, and keeping pets away from medical equipment and open wounds — is usually all it takes to keep the whole household, pets included, happy and healthy.
