Speaking of outbreaks, you may be wondering if your dog can get infected with the COVID-19 virus that’s spreading around the world. See the latest news in our article on coronavirus in dogs.

Article Overview


What Is Canine Flu?

Quote Form WidgetThe dog flu, or Canine Influenza Virus (CIV H3N2 or H3N8), is a highly contagious infection caused by an influenza virus and is transmitted by aerosolized respiratory secretions — think coughing and sneezing.

Causes: How Does A Dog Get The Flu?

Dog influenza can also be transmitted between dogs via contaminated objects such as food and water bowls, collars, leashes, toys, bedding, and through nose-to-nose contact between dogs.

The virus is able to live on surfaces for up to 48 hours, on clothing for 24 hours and on hands for up to 12 hours.

What Dogs Are At Risk Of The Flu?

Dogs that are most susceptible to infection are those that spend a good deal of time around many other dogs during boarding, day care or play time at the dog park.


Dog Flu Symptoms

“Most infected dogs have mild clinical symptoms and it can be very hard to distinguish from other forms of canine infectious respiratory disease complex (CIRD), a common type of kennel cough,” says Carrie Jelovich, DVM. So if your dog shows any of these symptoms, visit your veterinarian so they can test to confirm whether or not your dog has Canine Influenza H3N2.

Canine Flu Symptoms May Include:

  • Persistent cough
  • Nasal discharge – not just your dog’s normal wet nose
  • Fever
  • Eye discharge – look for goopy, mucus-like discharge or a noticeable increase if your dog normally has eye discharge
  • Reduced appetite
  • Reduced activity, lethargy

It’s important to recognize the symptoms of dog flu so you can seek treatment for your pet quickly.

Treating Dog Flu

The flu needs to run its course (15-30 days for mild cases). Treatment for canine flu is mostly supportive: fluids, rest and cough medicine prescribed by your vet. (Please don’t give human meds to dogs.) Very severe cases may require hospitalization or more intensive therapies.

Preventing Dog Flu

You may notice warning signs about the canine flu popping up at doggie daycares, boarding facilities, dog parks, veterinarian’s offices and even dog-friendly businesses. And for good reason: prevention is the best cure.

Here’s what you can do to help keep your pup from catching the bug and control the outbreak:

  • Stay home! Don’t you get annoyed when someone shows up to work hacking and sneezing all over the place? The same applies here: if your pooch is showing symptoms of dog flu, or has been diagnosed with canine influenza, keep them home and away from other dogs until they’re well. For the time being, you may want to limit your dog’s contact with other canines and avoid places where canine flu has been reported.
  • Speak up! If you absolutely must bring your dog to daycare or a boarding facility, ask if they’ve had any cases of dog flu and what they’re doing to prevent it from spreading. And visit your vet a few weeks prior to travel to determine whether the vaccine is a good option.
  • Wash your paws! If you can’t help petting every dog you see, wash up well before you spread the love – and the virus – to your own dog.

Here’s a recap of everything we’ve discussed and a little more about this flu and what to look out for from National Geographic.

A Few Dog Flu Facts

  • Dog flu is not usually fatal. Death rate is reported to be less than 10% among flu-infected dogs.
  • There is now a vaccine for both the H3N2 and the older H3N8 strains. Talk to your vet about the best option for you and your pup, especially if they spend a lot of time around other dogs.
  • You can’t catch the flu from your dog. This is highly unlikely since, according to the CDC, it would take a sizable cell mutation for a human infection from a dog CIV to infect you.
  • June 2018: A new strain was detected (H1N1) in dogs in China (no cases in the U.S. detected). This is related to the swine flu strain that infected humans in 2009. The CDC does not currently consider H1N1 or any other strain in dogs to be a threat for human infection. However, studies have shown it may be possible for the H1N1 virus to jump from dogs to cats.
  • May 2017: Canine flu H3N2 had shown up in dogs in Florida, Georgia, Illinois, Kentucky, Louisiana, Missouri, New York, North Carolina, South Carolina, Tennessee and Texas.
  • The 2015 canine flu outbreak (H3N2) has been traced back to Chicago. This virus was transferred from birds to dogs.

Keep Your Dog Protected With Pet Insurance

A big, tail-wagging thank you to Carrie Jelovich, DVM, for her contributions to this article in July 2015. Dr. Jelovich cares for critters at the Lawndale Veterinary Hospital in Greensboro, North Carolina.

As always, we can’t recommend getting dog insurance enough. It saves you from having to pay out of pocket expenses should an illness like dog flu arise unexpectedly.
