Canine Influenza (CIV): Canine influenza (CI), or dog flu, is a highly contagious viral infection affecting dogs and cats. Currently there are two strains that have been identified in the U.S., H3N8 and H3N2. It may be spread from an infectious dog to another dog through saliva, sneezing, barking or coughing, and other items such as water bowls, toys, or people spreading the virus from an infected dog to an uninfected one. The Canine Influenza Vaccine is similar to the flu vaccine in humans, it does not prevent the dog from getting Canine Influenza but with the vaccine, the dog's immune system will have a better ability to fight the virus. If your dog becomes ill, please always remember to keep them home, consult your vet and report to PupTown the illness.
