Canine Influenza (H3N8 Virus)

*The information given below is a summary from a Oregon Veterinary Medical Association publication*

     H3N8 is a canine influenza virus that causes respiratory infection in dogs.  Cases have been confirmed in numerous states, including Oregon.  The following information is to help give dog owners some answers to some questions, however, please contact your Veterinarian for more in depth information.

Transmission:  Canine influenza appears to be an airborne disease.  If your dog is in contact with other dogs thru boarding, puppy classes, showing, or doggy daycare, they may be at higher risk.  Humans, cats, horses, or other animals cannot catch this flu virus from dogs.

Symptoms:  The symptoms are those similar to kennel cough.  Most dogs experience a mild form of the disease, but may have a persistent cough that may last three weeks along with a yellowish nasal discharge which can be treated effectively with antibiotics. 

Dogs who become more seriously ill frequently have a high fever, exhibit increase respiratory rates, and other indications of bacterial pneumonia.  The fatality estimate rate is estimated to be between 5-8%.  Early diagnosis and treatment by a veterinarian is important.

If your dog develops a cough, especially if it has already received a Bordetella vaccine, call your veterinarian.  Do not take your dog to locations that it might encounter other dogs.  Be sure to tell your veterinarian if your dog has been boarded, gone to puppy classes, etc...

Remember, coughing can indicate other serious medical issues.  Your veterinarian is best qualified to diagnose your dog.

Prevention:  Avoid contact with ill dogs, wash your hands after handling any other dog, do not handle or touch dogs that are coughing or have yellowish nasal discharge.

The Bordetella vaccine DOES NOT protect your dog from canine influenza.  However, there is a vaccine for the canine influenza.  Please contact your veterinarian, or our office 503-640-0472 for information regarding the vaccination and to discuss whether or not your dog is at risk for canine influenza.
