Canine influenza is a relatively new infectious disease caused by two separate viral strains – H3N8 and H3N2. First reported in Florida in 2005, H3N8 was recognized after a group of racing Greyhounds became ill (many fatally) with a severe and extremely contagious pneumonia. It has since been documented in 42 states, including New Hampshire. A few years ago, there was a reported outbreak at a kennel as close to us as Ipswich, Massachusetts.
