Flu season is well underway in Massachusetts—and with it the body aches, congestion, fatigue and other ills associated with our collective seasonal misery. Now veterinarians at the MSPCA’s Angell Animal Medical Center in Boston are concerned about a second category of potential victims: dogs. There is zero risk of dogs contracting human flu—nor is there a canine flu epidemic underway in Massachusetts. However, several states, including Illinois, Georgia and Kentucky, are racking up hundreds of positive canine flu tests and that has the veterinary community concerned. “This flu season has been severe for humans and that’s why there is so much attention on flu right now,” said Dr. Virginia Sinnott of Angell Animal Medical Center.
