Concerned about your pet’s risk from the COVID-19 pandemic? The virus is primarily spread among people, and that time of fear and uncertainty around pets has created a lot of confusion. In this short blog post, we will eliminate myths, outline potential symptoms in cats and dogs and provide useful tips to keep your pets safe and healthy. Let’s take the fact from the fiction and make sure you and your pets are healthy and protected!

COVID IN DOGS AND CATS

Know about the Virus COVID In Dogs and Cats

SARS-CoV-2 is the virus that causes COVID-19. It mainly affects the lungs and makes it hard to breathe. People who have the virus can spread it when they cough, sneeze, or talk. Tiny droplets with the virus go into the air. It spreads easily from one person to another and caused a worldwide outbreak.

COVID-19 mostly affects people, but sometimes pets like cats or dogs can get it too, usually from their owners. However, it’s very rare for people to catch the virus from pets. Most pets that get the virus either have very mild symptoms or no symptoms at all.

You know, some studies suggest cats might catch COVID a bit easier than dogs; plus a few have shown breathing troubles. Looks like dogs maybe don’t catch that virus so much. Should they catch it, typically their symptoms are mild, even nonexistent.

While risk seems small it’s wise to do some simple safety checks for pet wellbeing.

Effects and affinity Of COVID (SARS-CoV-2) In Dogs and Cats:

Covid in dogs and cats virus has different structure, physical and chemical characteristics along with its affinity to them-

CategoryDetails
Virus NameSARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2)
Virus TypeEnveloped, positive-sense single-stranded RNA virus (ssRNA)
FamilyCoronaviridae
Shape & SizeSpherical or pleomorphic; 60–140 nanometers in diameter
Genome SizeApproximately 30,000 nucleotides (large for an RNA virus)
Structural Proteins– Spike (S) protein (binds to ACE2 receptor)
– Membrane (M) protein
– Envelope (E) protein
– Nucleocapsid (N) protein
EnvelopeLipid bilayer from host cell membrane; sensitive to heat and detergents
Spike Protein FunctionAttaches to ACE2 receptors on host cells to allow viral entry
Stability on SurfacesCan survive from a few hours to several days, depending on material and conditions
Heat SensitivityDeactivated at 56°C (133°F) within 30 minutes
Chemical SensitivityDestroyed by alcohol-based sanitizers, bleach, detergents
Affinity to CatsModerate to high: Cats have ACE2 receptors similar to humans; can get infected and show mild respiratory symptoms
Affinity to DogsLow: Dogs have less compatible ACE2 receptors; rarely infected, usually asymptomatic
Risk of Pet-to-Human SpreadVery low: No strong evidence of pets transmitting the virus back to humans

Why Covid Virus Is less Dangerous To Dogs AND Cats-

FeatureExplanation
Species-specific ACE2 ReceptorsSARS-CoV-2 binds to ACE2 receptors to enter cells. Cats have receptors more similar to humans than dogs, but both are less compatible overall compared to humans.
Low Viral Load in PetsInfected dogs and cats tend to carry a much lower amount of virus, reducing symptoms and transmission potential.
Mild or No SymptomsMost infected pets—especially dogs—show no symptoms or only mild ones like sneezing or coughing.
Limited Viral ReplicationThe virus doesn’t multiply efficiently in dogs’ or cats’ cells, which limits infection severity.
Weak Transmission Among PetsThere’s no significant evidence of sustained pet-to-pet or pet-to-human transmission in household settings.
Strong Immune Response in PetsSome pets may naturally clear the virus quickly due to an effective innate immune response.
Rare Cases of Severe IllnessVery few global cases of severe illness or death in pets due to COVID-19 have been reported.

Remember-

  • Cats tend to show more respiratory symptoms than dogs.
  • Most cases in both animals are mild or asymptomatic.
  • Serious signs of illness are uncommon and mostly seen in pets with other health problems or high exposure to the virus.
  • Best way is to consult a veterinarian if your pet shows unusual symptoms, especially after close contact with a COVID-positive person.

Vaccination of Covid in Dogs and Cats

Till now, there are no approved vaccines specifically for COVID-19 (SARS-CoV-2) in dogs or cats. The vaccines developed for humans are not suitable or authorized for use in pets. To get more information about vaccination, read our article regarding dog vaccination.

Know About Other Coronavirus Vaccines for Pets?

  • Dogs: There are vaccines for a different type of coronavirus that affects dogs called Canine Coronavirus (CCoV), which mainly causes gastrointestinal illness. This vaccine does not protect against COVID-19.
  • Cats: There is no widely used vaccine for feline coronaviruses like Feline Infectious Peritonitis (FIP) that also protects against SARS-CoV-2.

Current Recommendations:

  • If any person in your household is COVID-positive, restrict/minimize close contact with pets as a precaution.
  • Adopt good hygiene around pets,wash hands before and after touching/interacting with them.
  • Watch your pets for any symptoms if they have been exposed to infected humans.
  • Consult your veterinarian for the best care advice.

Research and Development:

  • Some experimental vaccines for animals against SARS-CoV-2 are in development or limited use in certain countries (e.g., Russia and China have developed COVID-19 vaccines for minks and some pets), but these are not widely available or approved globally.

Summary:

  • No standard COVID-19 vaccines for dogs or cats yet.
  • Existing pet coronavirus vaccines do not protect against COVID-19.
  • Preventive care and hygiene remain the best approach for now.

Human-to-Pet Transmission & Pet-to-Human Transmission-

Human-to-Pet Transmission

SARS-CoV-2, the virus causing COVID-19,during close contact can spread from humans to animals. Pets worldwide, including cats and dogs, have been infected with the virus, mostly after close contact chance of infection of covid in dogs and cats increases. CDC+4CDC+4CDC Stacks+4

Notable Cases:

  • United States (2020): Two domestic cats tested positive for SARS-CoV-2 after exposure to owners with COVID-19. Both cats showed mild respiratory symptoms and recovered. CDC
  • United Kingdom (2021): A pet dog contracted COVID-19, likely from its owners. The dog showed mild symptoms and recovered. The Guardian
  • South Korea (2021): A study found SARS-CoV-2 positivity rates of 24.0% for dogs and 35.6% for cats in households with confirmed human COVID-19 cases. CDC Stacks

Pet-to-Human Transmission

There is low chances of spreading spreading COVID-19 to people. Most animals became infected after contact with humans with COVID-19, and there is no proof that covid in dogs and cats play a significant role in spreading the virus to people.

Tests Used To Confirm Covid In Dogs And Cats-

Similar types of tests are used to diagnose COVID-19 in humans, dogs, and cats, though the procedures and settings may vary slightly. Here’s a comparison in tabular form:

Test TypeUsed in HumansUsed in Dogs & CatsPurpose
RT-PCR (Swab Test)✅ Yes✅ YesDetects active infection by identifying viral RNA. Most accurate.
Antigen Test✅ Yes✅ Yes (limited use)Detects proteins of the virus for quick results. Less accurate than PCR.
Antibody Test (Serology)✅ Yes✅ YesDetects antibodies indicating past infection. Not used for current diagnosis.
Viral Culture✅ Rarely used✅ Rarely usedGrows live virus in a lab for research. Not common in routine diagnosis.

Main Similarities:

  • RT-PCR and antigen tests are used to diagnose active infections in both humans and animals.
  • Antibody tests are used in both for research and retrospective analysis.

🐾 Key Differences:

  • Testing in humans is more routine and widely available.
  • Testing in animals is only recommended when necessary, usually when pets show symptoms after close contact with a COVID-positive person.
  • Veterinary labs handle pet samples, while human tests are processed in clinical labs or hospitals.

Prevention & Care Guidelines for COVID-Positive Pets

What to DoWhy It’s Important
Isolate the pet from people and animalsPrevents possible spread, especially to other pets.
Limit contact with the infected petAvoid petting, snuggling, kissing, or sharing food.
Use gloves and wash hands after contactReduces your risk of indirect transmission.
Avoid walking your dog in public areasKeeps other animals and people safe. Use a private yard if possible.
Keep your pet indoorsPrevents spreading the virus to outdoor animals or people.
Do not put a mask on your petMasks can make it hard for pets to breathe and may stress them.
Monitor for symptoms (like cough, lethargy, appetite loss)Contact your vet if symptoms worsen.
Clean bedding, bowls, and toys regularlyHelps reduce contamination in your home.
Follow your vet’s advice carefullyVets will guide you on testing, medication (if needed), and recovery.

✅ When Can Your Pet Be Considered “Recovered”?

  • After 14 days with no symptoms, and no contact with COVID-positive people.
  • Regarding all information of covid in dogs and cats adopt all practices, as advised by your veterinarian.

Reinfection in Pets – What We Know

AspectExplanation
Can pets get reinfected?Yes, but it’s very uncommon.
Why is reinfection rare?Most dogs and cats build short-term immunity after infection, just like humans.
What increases reinfection risk?Close contact with an infected person again, especially if the pet has low immunity or health issues.
Is reinfection more severe?No. Most reinfections are mild or asymptomatic, just like the first infection.
Is there long-term immunity?Not fully known, but evidence suggests pets may retain some antibodies for a few months.

🐾 Key Points:

  • Reinfection of covid in dogs and cats is not a major concern in them.
  • Practicing good hygiene and isolation if you’re sick helps prevent repeated exposure.
  • Regular vet checkups can help monitor your pet’s health post-infection.

Canine Coronavirus (CCoV) Transmission to Dogs and Cats?

Canine Coronavirus (CCoV) is not the same as COVID-19 (SARS-CoV-2). It is a different virus that affects mainly dogs and causes gastrointestinal illness, not respiratory disease.


Routes/Modes of Transmission – Canine Coronavirus (CCoV)

Transmission MethodDescription
Fecal-Oral RouteThe main transmission method. Dogs become infected by licking or eating contaminated feces or surfaces.
Contaminated EnvironmentsVirus can survive on surfaces like food bowls, cages, kennels, or soil, especially in crowded areas.
Close Contact with Infected DogsDirect nose-to-nose interaction or sniffing feces from an infected dog spreads the virus.
Shared food/water bowlsIf an infected dog shares bowls, toys, or bedding, the virus can be passed on.
Human Hands or Clothing (Indirect)Not common, but people can unknowingly carry virus particles on hands or clothes.

Cats Get Canine Coronavirus?

  • Very rare: Cats can be infected by their own version of coronavirus (Feline Coronavirus, FCoV), which is different from CCoV.
  • No strong evidence that cats get sick from Canine Coronavirus.

🚫 Can Humans Get CCoV?

  • No. Canine Coronavirus does not infect humans.

🐾 Prevention Tips:

  • Keep your dog away from feces in public spaces.
  • Clean food and water bowls daily.
  • Avoid overcrowded kennels or dog parks with poor hygiene.
  • Practice good handwashing after handling dogs or cleaning up after them.
