What Is Canine Influenza Virus?

The canine influenza virus, commonly known as dog flu, is a contagious respiratory disease that affects dogs. It is caused by two different influenza virus strains, namely H3N8 and H3N2. The virus spreads through respiratory secretions from infected dogs, such as coughing, sneezing, or direct contact with contaminated surfaces. Canine influenza can lead to respiratory symptoms such as coughing, nasal discharge, fever, lethargy, and reduced appetite. In some cases, it can progress to more severe respiratory infections or pneumonia. Vaccination is available to prevent canine influenza, and prompt veterinary care is essential for affected dogs to manage symptoms and prevent complications.

Have you ever heard of the canine flu? Also known as the canine influenza virus (CIV), this viral illness has become a growing concern for pet owners across the country. According to recent statistics, over 80% of dogs that are exposed to CIV will become infected, making it important for us to educate ourselves and protect our furry friends from this serious illness. In this article, we’ll dive into the world of canine flu, exploring its symptoms, causes, and ways to prevent its spread. So, let’s get started!

What Is Canine Influenza Virus?

There are many causes of kennel cough, both bacterial and viral. One of the reasons dogs get kennel cough is because of a virus called Canine Influenza Virus (CIV). This highly contagious respiratory disease has affected thousands of dogs in the United States. Because CIV is a relatively new virus, most dogs have not been exposed to it before. Dogs of any age, breed, and vaccine status are susceptible to this infection.

How Could My Dog Catch Canine Influenza Virus?

CIV can easily be transmitted between dogs through a combination of aerosols, droplets, and direct contact with respiratory secretions. The virus does not survive for a long time in the environment, so dogs usually get CIV when they are near other infectious dogs.

Which Dogs Are Prone to Canine Influenza Virus?

Any dog who interacts with many dogs is at increased risk for exposure. There is not yet a vaccine available to prevent CIV.

What Are the General Symptoms of Canine Influenza Virus?

While most dogs will show typical symptoms of kennel cough, a small percentage of dogs will develop a more severe illness. Symptoms of the canine influenza virus include:


      • Coughing
      • Sneezing
      • Variable fever
      • Clear nasal discharge that progresses to thick, yellowish-green mucus
      • Rapid/difficult breathing
      • Loss of appetite
      • Lethargy

    Can Dogs Die from Canine Influenza Virus?

    Yes, if a dog has CIV and doesn’t get treated right away, it could die. But if they get a diagnosis and the right care, most dogs with CIV recover. The main thing that can cause a dog with CIV to die is a different illness, like pneumonia, that they get while they have CIV. So, it’s super important to take your dog to the vet if they have CIV.

    The canine Influenza Virus is a serious illness that can affect dogs. While it is not always fatal, it is important to be aware of the risks and to take steps to keep your dog healthy and protected. With early diagnosis and proper veterinary care, most dogs recover from CIV and go on to lead happy healthy lives. It’s important to always keep an eye out and stay up-to-date on the latest information about CIV. That way, you’ll have all the information you need to make the best decisions for your pet’s health.

    How Is Canine Influenza Virus Diagnosed?

    Your vet might examine your dog thoroughly and do some tests to figure out if they have Canine Influenza Virus (CIV).

    They may take a sample of your dog’s nasal discharge, blood, or saliva to test for the presence of the virus. If your dog is sick, it’s important to take them to the vet. The vet will check them out and do some tests to see what’s wrong. These tests will help the vet figure out how sick your dog is and what the best way to treat them is. It’s also important to keep your sick dog away from other dogs so that they don’t get sick too, and to wash your hands after handling them. If you suspect your dog may have CIV, it’s important to contact your veterinarian right away to get an accurate diagnosis and start appropriate treatment.

    How Is Canine Influenza Treated?

    Because CIV is a virus similar to the flu in humans, there is no specific antiviral medication available. However, supportive care and appropriate treatment of secondary infections are important. Your vet might tell you what to do to help your dog feel better while they’re dealing with cataracts:


        • Good nutrition and supplements to raise immunity
        • A warm, quiet, and comfortable spot to rest
        • Medications to treat secondary bacterial infections
        • Intravenous fluids to maintain hydration
        • Workup and treatment for pneumonia

      Did you know that if your dog gets Canine Influenza Virus (CIV), it may get better on its own within 10 to 30 days? But sometimes, they might get sick again because of another infection. That is why it’s important to give them antibiotics and sometimes, they may even need to stay in the hospital.

      What Should I Do if I Think My Dog Has Canine Influenza Virus?

      If you think your dog has the canine influenza virus, immediately isolate him from all other dogs and call your veterinarian.

      Can I Catch Canine Influenza from My Dog?

      No. There is no evidence that dogs can transmit CIV to humans.

      To prevent your dog from spreading the disease, it’s important to keep them isolated for 10 to 14 days if they are infected with CIV. Even before they show any symptoms, they can still spread the virus. So, if you see any symptoms, make sure to keep them away from other dogs to prevent the spread of the virus.

      To help prevent the spread of CIV, make sure your dog is up-to-date on their vaccinations and consider getting a vaccine for the virus. It’s also important to keep your dog away from places where other dogs gather, like dog parks and boarding facilities, if they are showing any signs of illness. When visiting the vet, keep your dog on a leash and away from other dogs to prevent any possible transmission of the virus. To help stop the spread of CIV, it’s important to follow some simple steps. For example, wash your hands after petting your dog and clean things they may have licked or drooled on. That will keep the virus from spreading to other dogs. By following these steps, you can help protect your dog and others from the spread of CIV.

      I Foster/Work with Multiple Dogs. What Advice Do You Have for Me?


          • The risk of CIV is always present. That’s why it’s important to work with a veterinarian to develop a plan of action in the event of an outbreak. You’ll want to diagnose and treat the issue promptly.
          • Routinely watch animals for signs of illness and keep medical records.
          • Isolate sick animals from healthy animals, especially those with signs of respiratory disease.
          • Wash hands with soap and water after handling each animal.
          • Gloves should be worn when handling infected dogs or cleaning contaminated cages.
          • Use antibiotics with care.
          • Remember that CIV is generally a very treatable disease.
