Canine Flu

Did you know that your beloved dog can catch the flu just like humans do? Canine flu, caused by the highly contagious canine influenza virus (CIV), is currently spreading rapidly across the country. This virus, with common strains like H3N8 and H3N2, poses a serious risk to dogs, especially in communal spaces like parks, daycares, and grooming salons. Understanding the symptoms, methods of transmission, and steps to protect your furry friend is crucial in keeping them safe during this outbreak. Read on to learn more about how to protect your pet.

Symptoms

If Fido gets the flu, he’ll likely have many of the same symptoms as you would, such as coughing, nasal discharge, fever, lethargy, and reduced appetite. Of these, coughing is the most common. It may also be the most persistent. That said, our furry friends all react differently to the flu. Some pups will not show any symptoms at all. Other dogs may bounce back after a few days, or stay sick for weeks. A few will become severely ill. In rare cases, dog flu can be fatal. Senior dogs and pooches with chronic illnesses and/or immune deficiencies are at highest risk.

Spread

Fido’s flu can spread extremely quickly. The virus is transmitted through droplets of saliva, and can remain active in respiratory droplets on surfaces for several hours. Pups can easily contract it through shared toys or dishes. Fido could also get sick by greeting or nose-booping another pooch, or even just by sniffing a stick at a park that a sick dog played with hours ago.

Dogs that have contracted the flu remain contagious for about a month. As one can imagine, places like dog parks, daycares, grooming salons, and kennels can quickly become hotspots of contagion. Another potential source of spread? People! Someone who pets an infected dog and then a healthy one may quickly spread the illness from pooch to pooch. Be aware of the risks when taking Fido to different places. You can also track the current outbreak online here.

Treatment

Unfortunately, there is no cure for the canine flu. In most cases, dogs recover on their own, though they may need some extra TLC. You’ll need to keep your furry pal comfy and hydrated, and monitor him carefully. If you know or suspect that your pup has the flu, reach out to your vet and ask for specific care tips.

Understanding Canine Flu in 2024: Strains, Diagnosis, and Transmission of Dog Influenza

What are the specific strains of canine influenza virus?

The specific strains of canine influenza virus commonly found in the US are H3N8 and H3N2. Both strains are highly contagious among dogs. Initially identified in horses, the H3N8 strain jumped to dogs and has since been a prevalent cause of canine influenza. The H3N2 strain, first observed in Asia among birds, was later reported in dogs in the United States around 2015. These strains can lead to symptoms like coughing, nasal discharge, and fever, and they spread through direct contact or contaminated surfaces.

How is canine influenza diagnosed?

Canine influenza is diagnosed primarily through clinical symptoms such as coughing, nasal discharge, and fever. For confirmation, veterinarians may use specific tests, like polymerase chain reaction (PCR) testing, which detects the presence of the virus in a dog’s respiratory secretions. Additional diagnostic methods include serological testing to identify antibodies that indicate a recent infection. These tests are critical in distinguishing canine influenza from other respiratory illnesses in dogs, ensuring that appropriate management and care strategies are implemented.

What is the incubation period and how long are dogs contagious?

The incubation period for canine influenza, or dog flu, generally lasts 2 to 4 days post-exposure before symptoms appear. However, this can vary based on the strain and the individual dog’s health. Once symptomatic, dogs are highly contagious, capable of spreading the virus for up to 4 weeks, even as they recover. Due to the rapid spread through saliva and respiratory droplets, vigilant monitoring and isolation from other dogs during this period are crucial to prevent further transmission.

Are there vaccines available for canine influenza?

Yes, vaccines are available for canine influenza, specifically targeting the H3N8 and H3N2 strains. These vaccines can help reduce the severity and spread of the disease but may not prevent it entirely. Vaccination is particularly recommended for dogs frequently exposed to areas with high dog traffic, such as kennels, dog parks, and grooming salons. Consult with a veterinarian to determine if the vaccine is suitable for a dog’s specific health conditions and lifestyle. Regular vaccination can play a crucial role in controlling outbreaks and protecting canine health.

Can cats or humans contract canine influenza?

Canine influenza, specifically the H3N8 and H3N2 strains, is a highly contagious virus affecting dogs, but it does not pose a risk to cats or humans. Research has shown that these strains are species-specific to canines and have not been documented to cross-infect humans or felines. Cats and humans are susceptible to their own species-specific strains of influenza, which are distinct from the canine variants. Therefore, while taking precautions in environments where the virus is present is wise, there is no direct threat to cats or humans from the canine influenza virus.
