Canine influenza is a highly contagious respiratory disease that is caused by canine influenza virus (CIV) Type A. There are 2 known strains in the United States: H3N8 and H3N2. Most unvaccinated dogs are susceptible to infection by both viruses.

Which dogs are at risk?
Any dog can be at risk for canine influenza regardless of age, sex, or breed. However, dogs that visit doggie day cares, boarding kennels, dog parks or attend dog events are at more risk.

How is canine influenza spread?
Canine influenza spreads the same way as the common cold in humans.

These viruses are most commonly spread through direct dog contact (sniffing, licking, nuzzling); through the air (coughing and sneezing); via contaminated surfaces (sharing water bowls or toys); or through contaminated humans (with viruses on their hands or clothing).

Where could my dog catch canine influenza?
The more your dog socializes with other dogs, the higher the risk of contracting canine influenza and other infectious respiratory diseases.
