In some ways, canine flu is similar to “kennel cough,” which is caused by a bacterial or viral infection and can infect dogs at any time of the year.1 Of course, not all dogs will necessarily benefit from a canine flu shot, but dogs that have frequent contact with other dogs will likely benefit the most from vaccination.
