Key takeaways:
Dogs can get colds, but the viruses and bacteria that cause upper respiratory infections in dogs are not the same as those that affect humans.
Different viruses affect different species, so it is nearly impossible for you and your dog to catch colds from each other.
Symptoms of colds in dogs are almost identical to other respiratory illnesses, so you should always contact your vet.
Sneezing, coughing, walking around with a handful of tissues — we’ve all been there. Cold and flu season is nothing to sneeze at. These common viruses spread through schools and offices, knocking many people down for a day or two.
But what about your dog? Can they also get a cold? And can they catch one from you or vice versa?
Keep reading to discover what symptoms indicate that your dog has a cold or another respiratory illness and what you should do.
Yes, dogs can get infections that cause cold-like symptoms, such as sneezing or coughing.
Cold symptoms in dogs are often caused by common upper respiratory tract infections, including:
Canine respiratory coronavirus
Canine herpesvirus-1
Canine distemper
Canine adenovirus type 2
Bordetella bronchiseptica
Mycoplasma species bacteria
Zooepidemicus
But cold symptoms can also be caused by illnesses such as:
Bronchitis
It is nearly impossible for your dog to catch your cold because different viruses and bacteria affect different species. Your dog can get an upper respiratory infection. But it is unlikely to be a virus that causes the human cold.
Runny noses: A cold isn’t the only reason your dog might have a runny nose. Learn about other potential causes of this common symptom.
Kennel cough: It’s helpful to understand what kennel cough is, especially if your dog frequently spends time with other pups. Check out common kennel cough symptoms.
Seasonal allergies: Just like humans, dogs can develop seasonal allergies. Find out what to expect if your dog gets itchy with the change of seasons.
When your dog has a cold, they may have many of the same symptoms humans get. Common cold symptoms in dogs include:
Runny or stuffy nose
Open-mouthed breathing
Coughing
Sneezing
Watery eyes
Pawing at their face
Snoring
Less energy
Very young puppies and old dogs are at greater risk of developing respiratory diseases than healthy adult dogs. Make an appointment with the vet if your dog or puppy has cold symptoms along with any of the following:
Appetite changes
Vomiting
Diarrhea
Depending on the cause, your dog’s cold symptoms may last 1 to 2 weeks. Let your vet know if symptoms persist or get worse.
Like human colds, there is no specific treatment for dog colds. Generally, you can care for your dog at home as they recover from respiratory infections. Do not give your dog over-the-counter medications without talking to your veterinarian.
As your dog waits out a cold or respiratory infection symptoms, any of the following suggestions may help them feel better.
Create a soothing, comfy area for your pup to recover. Give plenty of extra blankets and pillows and let your pup rest in a quiet spot away from distractions.
Use steam or a humidifier to help your dog’s breathing. If you don’t have a humidifier, bring your dog into the bathroom and run a hot shower.
Set out plenty of fresh water for your dog. Add a little low-sodium chicken broth to some of their water to encourage them to drink extra fluids.
Just like humans, when dogs have a stuffy nose, they can’t smell as well. This can make them less interested in food.
If you feed your dog wet food, try heating it in the microwave for a few seconds to make it smell more appealing. You can also try adding low-sodium chicken or beef broth to your dog’s food to encourage eating.
Don’t rush your dog back into exercise until they have recovered. Then, slowly ease back into their usual exercise routine.
It’s unlikely that you will give your cold to your dog or vice versa. But upper respiratory infections can be transmitted from one pet to another. Until your dog feels better, try to separate them from other pets in the house to prevent any infections from spreading.
Do not give your dog over the counter medications for their cold (especially not medication intended for human use). Your veterinarian will let you know if your dog’s symptoms require medications, and they’ll tell you which cold medicine is appropriate for your dog.
If your dog has a secondary bacterial infection, such as pneumonia, your veterinarian may prescribe medications. This might include antibiotics and cough suppressants. Check back with your vet if your pup’s symptoms don’t clear up or if a cough persists beyond 21 days despite antibiotic treatment.
Check in with your vet’s office when you notice your dog’s symptoms. The vet knows your dog’s health history and may have insight into which dog viruses are currently spreading. Take your dog to the vet right away if they experience:
Trouble breathing
Retching or gagging
Loss of appetite for more than 2 days
Otherwise, mild cold-like symptoms aren’t usually cause to worry. But the symptoms of canine colds are almost identical to other respiratory illnesses. So you’ll want to rule out other causes of your dog's respiratory symptoms.
The best way to prevent your dog from catching a cold is to make sure they are up to date on their vaccines. Vaccines can prevent several of the common causes of cold symptoms in dogs, including:
Canine parainfluenza
Canine adenovirus type 2
Canine distemper
Bordetella bronchiseptica
A dog who is congested or has a stuffy nose may sound like they are breathing through their mouth. They may also snort or sneeze.
Follow your dog’s lead. Some dogs may spend more time than usual by themselves or resting in their crate or bed. Other dogs might prefer to spend more time than usual cuddled up next to their favorite people.
Dogs get colds just like humans do. But despite similar symptoms, they’re not caused by the same infections. Cold-like symptoms in dogs can be caused by many different bacteria and viruses. Treat your dog’s sniffles a bit more seriously than you might treat your own cold symptoms to rule out possibly dangerous infections. Keep in mind, there is no cure for the canine cold. But there are vaccinations for some of the viruses and bacteria that cause upper respiratory illnesses in dogs.
