Dog flu, caused by the canine influenza virus (CIV), occurs year-round and can affect dogs of any breed, age, sex or health status. Almost all dogs exposed to the virus become infected, with 80 percent of those infected developing flu-like illness. Although CIV is highly contagious, it does not transfer to people.
At this time, Newberg Veterinary Hospital recommends vaccinating against the dog flu that are at risk of exposure or dog’s whose owners are concerned. Dogs at highest risk of contracting canine influenza are dogs who travel to areas with a high incidence of the disease (see https://www.dogflu.com/outbreak-map), go to dog shows or dog events, attend day care or are boarded or groomed. Our veterinarians can discuss your dog’s individual risk of exposure and the benefits of vaccinating against canine influenza.
Vaccination requires an initial vaccine with a booster vaccine 2-4 weeks after the initial vaccine. We vaccinate for both the H3N8 and H3N2 strains of the disease for maximum protection.
Please see below for more detailed information about canine influenza, brought to you by the American Veterinary Medical Association.
The canine influenza virus travels from infected dogs to uninfected dogs through:
- Direct contact
- Coughing, barking and sneezing
- Contaminated objects such as clothing, kennel surfaces, food and water bowls, collars and leashes
- People handling or moving between infected and uninfected dogs
Symptoms range from mild to severe and include:
- Nasal or eye discharge
- Reduced appetite
- Secondary bacterial infection can develop and may cause more severe illness and pneumonia
- Talk to your veterinarian about your dog’s risk of exposure and if the canine influenza vaccine is right for your dog
- Avoid exposing your dog to obviously sick dogs
- If there is a CIV outbreak in your area, avoid taking your dog to places where dogs gather
- If your dog shows signs of illness, isolate it from other dogs and seek veterinary care
- Wash your hands after handling any dog and especially after handling a sick dog
- Do not share equipment or toys between sick and apparently healthy dogs
- Provide supportive care to keep the dog as comfortable as possible
- Medications may be necessary for severe illness or secondary bacterial infections
- Most dogs recover within 2-3 weeks
