Animal Medical Care Canine Influenza H3N8

Canine influenza H3N8 first emerged in the United States in 2004 as a transfer from horses. It has now been confirmed in 34 states, including Oregon. This virus is highly contagious among closely housed dogs, but not transferred to people.

Signs of the disease can include a fever, harsh cough, and a green to yellow nasal discharge. Some dogs that have the virus may be asymptomatic. It is rarely fatal though dogs can be quite ill for several days and even develop secondary bacterial pneumonia.

There is a vaccine available that has proven to prevent or lessen the severity of the disease for dogs. We encourage the vaccine for dogs that are going to be in boarding or day care facilities.
