Human influenza, meanwhile, is widespread in every state but Hawaii. It continues to be a devastating flu season with rising death counts across the country, though some experts think the worst may be over.
Humans cannot catch canine influenza from dogs. Dog flu causes upper-respiratory infections with symptoms similar to the human flu, or kennel cough: coughs, runny snouts and lethargy that can last as long as four weeks. It has been diagnosed since 2004.
Canine companions may be joining their human owners in suffering through a particularly rough flu season.
Frandle recommended vaccination during a Q&A with Mercury News, adding that owners should keep their dogs away from other animals.
Outbreaks of the contagious illness have been reported nationwide, most notably on the West Coast, including the San Francisco Bay Area near San Jose as well as Washington.
