Are all dogs at risk of contracting the canine influenza virus?
Yes, all dogs, regardless of breed or age, are susceptible to infection. They have no naturally acquired or vaccine-induced immunity. Virtually 100 per cent of exposed dogs become infected. Nearly 80 per cent of infected dogs will contract a form of the disease which will produce obvious signs of illness. Of these, a small percentage of dogs will experience more severe clinical progression, including pneumonia.
