If you have the flu, it’s normal to worry about your dog. You’re close. Your dog licks you. You share the same air at home. So… can your dog catch your flu?
For typical seasonal human flu, it’s very uncommon for dogs to catch it from people. Dogs usually get their own respiratory viruses (like canine influenza), which spreads mainly dog-to-dog. Still, basic hygiene is smart when you’re sick.
First, “human flu” and “dog flu” are not the same thing
This is where people get confused.
Human flu (seasonal influenza)
This is the flu people catch during flu season.
Dog flu (canine influenza)
Dog flu is a contagious respiratory illness in dogs caused by specific influenza A viruses that infect dogs (commonly H3N2 and historically H3N8 in the U.S.). It spreads mainly when dogs are around other dogs (daycare, shelters, boarding, dog parks).
So if your dog gets “flu-like” symptoms, it’s usually not because you sneezed near them. It’s more often because your dog was exposed to another dog (or a place where many dogs were).
So… can dogs catch the flu from humans?
In everyday life, it’s rare
Most trusted pet health sources say there’s no solid evidence that typical human seasonal flu commonly infects dogs. That matches what many vets tell families: your dog usually won’t “catch your flu” the way another person would.
But influenza viruses can jump species sometimes (uncommon)
Influenza A viruses can infect many animals, and scientists have found evidence that dogs can be exposed to some human influenza strains in rare situations (usually shown by antibodies in studies). This is not the common household pattern, but it explains why experts avoid saying “impossible.”
Bottom line you can follow
If you have seasonal flu at home, your dog is far more likely to stay fine than to get influenza from you. But it’s still smart to use hygiene rules while you’re sick—because it’s easy and protects everyone.
What you should do when YOU have the flu (simple rules)
These steps are realistic and don’t require panic.
1) Avoid face licking while you’re sick
Not because your dog will “definitely” get flu, just because it’s cleaner and reduces germ sharing.
2) Wash hands before food and treats
If you’re coughing/sneezing, wash hands before you handle your dog’s treats, toys, bowls, or water.
3) Don’t share food, spoons, or cups
Sharing human food while you’re sick is a bad idea anyway. Some human foods also aren’t safe for dogs.
4) Keep your dog’s routine calm
Stress makes many pets more sensitive to illness. Keep sleep, water, and feeding normal.
What symptoms to watch for in your dog
If your dog catches a respiratory bug (from anywhere), symptoms can look “flu-like.”
Watch for:
- Coughing that lasts more than a day or two
- Sneezing or runny nose
- Low energy (more tired than normal)
- Reduced appetite
- Fever (hard to confirm at home, but your dog may feel hot and act unwell)
Dog flu symptoms often look like cough, nasal discharge, fever, and lethargy, and cough can last days to weeks in some cases.
When to call a vet (don’t wait)
Call your vet quickly if you notice:
- trouble breathing, fast breathing, or belly breathing
- blue/gray gums
- repeated vomiting with weakness
- your dog is very young, very old, or has heart/lung disease
- symptoms are getting worse, not better
A super important note: you can carry dog flu between dogs
Even if humans don’t “catch dog flu,” people can move germs on clothing/hands between dogs (for example: you pet a coughing dog at daycare, then touch another dog). This is why good hygiene matters if your dog has been around other dogs recently.
Common mistakes (that make things worse)
Mistake 1: Assuming every cough is “the flu”
Dogs can cough for many reasons (kennel cough complex, allergies, irritation). A vet can help you figure out which it is.
Mistake 2: Taking a coughing dog to daycare “because they seem okay”
Respiratory bugs spread fast in dog groups. If your dog coughs, keep them home until your vet advises.
Mistake 3: Giving human flu medicine to dogs
Many human meds are unsafe for dogs. Always ask a vet first.

Can dogs catch the flu from humans?
For typical seasonal human flu, it’s very uncommon. Dogs usually get different respiratory viruses, and canine influenza spreads mainly dog-to-dog.
-
What’s the difference between dog flu and human flu?
They are caused by different influenza viruses. Dog flu (canine influenza) is a contagious respiratory illness in dogs and usually spreads where dogs mix closely, like daycare or shelters.
-
Can my dog get sick if I’m coughing and sneezing?
Your dog is unlikely to catch your seasonal flu, but basic hygiene is still smart. Avoid face licking while you’re sick and wash hands before handling treats and bowls.
-
What symptoms of dog flu should I watch for?
Common signs include coughing, sneezing, runny nose, low energy, reduced appetite, and sometimes fever. Contact your vet if breathing looks hard or symptoms worsen.
-
Can humans spread dog flu between dogs?
Yes. People can move respiratory germs on hands or clothing between dogs, especially after contact with sick dogs or high-risk places like shelters and daycare.
