Amid the deadly flu outbreak hitting nearly every state in the U.S., even your furry best friend is not immune to the flu.
Canine influenza A H3N2 virus, or dog flu, was identified in the U.S. in 2015 and has infected dogs in nearly every state since then.
Dog flu is different from the strain of influenza that affects humans. All U.S. states except Hawaii are reporting widespread flu activity this season, according to the Centers for Disease Control and Prevention.
