WHAT IS IT?
Canine influenza virus (CIV) causes respiratory symptoms similar to those experienced by humans with the flu, including coughing, sneezing, lethargy, fever, and discharge from the nose and eyes. There are two known influenza virus types that can infect and spread between dogs in the United States.
IS THERE A VACCINE FOR CANINE INFLUENZA?
There are now vaccines available in the United States for both CIV H3N2 and CIV H3N8. Although both types of CIV are H3 viruses and share some traits in common, it is important to understand that they are different viruses requiring separate vaccinations. To date there is no information indicating that dogs vaccinated for one type will be protected against the other.
