Canine Influenza Information

Flu and flu like symptoms are on the news quite often this time of year. If you’re a dog owner, you may have heard of canine influenza. However, you may not be sure what it is or whether you should be concerned. Below, we’ve gathered all the information you need to stay ahead of the curve.

Canine Influenza (H3N8) is a new canine virus first identified in 2004 in racing dogs in Florida. The virus appears to have mutated from an equine strain of influenza. The Canine Influenza Virus (CIV) is an entirely different virus than the bird, swine, or human flu and has not affected people. Even though the virus has spread to 30 states, it is still relatively uncommon in most pets and has caused death in 5-8% of dogs infected with the disease.

Symptoms of canine influenza include a cough, purulent nasal discharge, and high fever (104-106) and occur 5-7 days after exposure to the virus. Cough can last 2-3 weeks after infection. Some dogs may not display symptoms of the disease, but can spread the virus to other dogs.

It is important to know that many other diseases cause these signs, so not every case of respiratory disease can be attributed to canine influenza. Treatment for CIV includes supportive care and antibiotics, although most dogs with mild cases will recover with routine veterinary care.

A new vaccine (Internet/Shering Plough) is available for CIV and has a conditional license by the USDA. The vaccine is believed to decrease the symptoms and helps control the disease spread widespread vaccination for CIV is not currently done in LV. However, pet owners should check with their veterinarian regarding vaccination recommendations.

There is not a simple, quick test for CIV, however veterinarians can send blood samples to a diagnostic lab if a diagnosis is needed. Pet owners should not panic, since only a single case of CIV has been diagnosed locally and most cases are mild in nature. Basic preventative steps for respiratory infectious disease include quarantining new or sick dogs, good hygiene with disinfection and hand washing, and avoiding unnecessary contact with other dogs especially if your dog is old, young, or has a compromised immune system.

The good news is that most dogs are not at risk for becoming sick with CIV. It is not necessary to keep your dogs inside. Please feel free to call our hospital or talk with any one of our veterinarians on your next visit if you would like more information about canine influenza.
