Some may remember back in 2004, several greyhounds at a Florida racetrack became infected with what was known as the equine flu virus, or H3N8. That flu spread to 42 states, including Virginia, and a vaccine was subsequently developed for that flu. Eleven years later, in 2015, another dog flu emerged — this time in Chicago. There have been no reported cases of canine influenza, also known as H3N2, in the state. But Virginia is surrounded by states where dog flu is present. A recent map of the dog flu outbreak in the country paints a picture that Virginia can feel both good and bad about.
