Can Pets Catch or Spread COVID-19?

If you've had COVID-19 and share your home with a dog or cat, it's a fair question: can they catch it and could they pass it back to you or someone else? The evidence here is reassuringly clear on the second point, even though the first is genuinely possible.

Can pets catch COVID-19?

Yes. Pets including cats, dogs, hamsters and ferrets have been documented catching SARS-CoV-2, with most of these cases traced back to close contact with an infected person rather than from another animal or the environment. Under natural conditions, pet cats appear somewhat more susceptible than dogs, though both can become infected after close and prolonged contact with someone who has COVID-19.

Can pets spread COVID-19 to people?

This is where the evidence is most reassuring. The World Health Organization has stated plainly that there is no evidence a dog, cat or any pet can transmit COVID-19 to a person. The CDC takes the same position, noting there is currently no evidence that companion animals can spread the virus to people. The overall risk of animals passing COVID-19 to humans is considered low and there's no proof the virus can spread to people from a pet's fur, skin or hair either.

What symptoms do infected pets show?

Of the relatively small number of documented cases in cats and dogs, some animals showed no symptoms at all and most that did become unwell had only mild symptoms. Pets have rarely become seriously ill from COVID-19, which is a meaningfully different picture from the range of severity seen in humans.

How does a pet typically become infected?

The clear pattern in research is that pets catch COVID-19 from their owners, not the other way around. An infected person shedding virus in their home, particularly through close, prolonged contact like sleeping in the same bed or being regularly cuddled and kissed by an infected owner, creates the conditions where transmission to a pet is most likely to happen.

Should you avoid your pet if you test positive?

Sensible precaution is reasonable even though the risk to your pet is generally low and the risk of them passing it back to you is essentially negligible based on current evidence. If you test positive, treating your pet the same way you would treat other household members, avoiding close face contact and having someone else handle feeding and walks where possible, is a reasonable precaution during your infectious period, more to protect your pet's comfort than out of a serious transmission concern in either direction.

What about other animals?

Beyond typical household pets, a range of other animal species have been found susceptible to SARS-CoV-2 in various studies, including some wildlife and farmed animals. This has been of more interest to researchers studying how the virus behaves across species and where new variants might emerge, than as a practical everyday concern for pet owners, since the household-pet evidence remains consistently reassuring about transmission back to humans.

Should you get your pet tested if you're worried?

Routine testing of pets isn't generally recommended or widely available and given that infected animals are usually asymptomatic or only mildly unwell and pose no meaningful risk of infecting you, there's typically little practical reason to test. If your pet does show concerning symptoms, like persistent lethargy, breathing difficulty or loss of appetite, that's a reason to contact a vet regardless of a possible COVID-19 connection, since these symptoms warrant veterinary attention on their own merits.

How different countries have approached animal surveillance

National animal health agencies in a number of countries, working alongside veterinary bodies, set up specific surveillance programmes during the pandemic to monitor SARS-CoV-2 in companion animals, farmed animals such as mink and wildlife, since understanding how the virus behaves across species matters for tracking where new variants might emerge. This international surveillance work is largely separate from everyday pet ownership concerns, but it's part of why the reassuring picture around household pets specifically has remained consistent across so many different countries and research groups rather than resting on just one or two studies.

Veterinary and public health authorities have generally coordinated closely on this issue, which is part of why the WHO, CDC and equivalent bodies elsewhere have all converged on the same core message about the low risk pets pose to their owners, despite the political and institutional differences between them on many other topics.

What about multi-pet households or shared spaces?

If you have more than one pet at home and test positive for COVID-19, the same general precautions apply across the household rather than needing anything species-specific beyond what's already been covered, since the documented risk relates to close contact with an infected person rather than pet-to-pet transmission being a major additional concern in most ordinary households. Shared spaces like communal gardens or dog parks haven't been identified as meaningful transmission risk points either, since the evidence consistently points back to close, prolonged household contact as the setting where pet infections actually occur, rather than incidental outdoor encounters between animals.

Veterinary clinics themselves generally didn't need to introduce COVID-19-specific precautions for routine appointments beyond the general infection control measures many already had in place, though owners who were themselves symptomatic were often asked to arrange for someone else to bring the pet in where possible, similar to how many other healthcare settings handled visitor policies during periods of higher transmission.

What owners can practically take away from the research

Stepping back from the individual details, the overall body of evidence built up since 2020 has been remarkably consistent across many different countries and research groups, which counts for a lot in a field where early pandemic findings sometimes shifted as more data came in. The core message, that pets can occasionally catch COVID-19 from their owners but pose essentially no risk of passing it back, has held up well over several years of continued monitoring rather than being revised as more evidence accumulated, which gives it a solid basis for the kind of everyday reassurance offered here.

For most pet owners, the practical takeaway is simple: normal life with your pet can continue as usual, with the modest precautions described above worth following specifically during your own infectious period, more out of general good practice than because the risk to your pet, or from your pet, is especially high.

A quick recap

Pets, particularly cats and dogs, can catch COVID-19 from an infected owner through close contact, though documented cases have generally been mild. Both the WHO and CDC agree there's no evidence pets can pass COVID-19 back to people, so while sensible precautions during your own infectious period are reasonable, there's no need for serious concern about your pet as a source of infection for your household.

Frequently asked questions

Can my cat or dog give me COVID-19 if they catch it from someone else?

Current evidence from the WHO and CDC doesn't support pets transmitting COVID-19 to people, regardless of how the pet itself became infected.

Should pets wear masks or be kept away from visitors?

This isn't recommended or necessary based on current evidence, since the transmission risk from pets to people hasn't been demonstrated.

Are some pet breeds or species more at risk than others?

Cats appear somewhat more susceptible to infection than dogs based on available research, though documented cases in both remain relatively uncommon overall.

Can I still cuddle my pet if I don't have COVID-19?

Yes, normal contact with a healthy pet carries no particular COVID-19 concern; the precautions discussed here relate specifically to periods when you yourself are actively infected.

Is there a COVID-19 vaccine for pets?

Some veterinary vaccines for animal coronaviruses exist for other purposes, but there is no widely available, specifically COVID-19-targeted vaccine for household pets, reflecting the low priority given the minimal risk pets pose to human transmission.
