The combination Canine Bivalent Influenza Vaccine is a lifestyle vaccine. It should be considered for dogs who frequently interact with other dogs or spend time in high canine traffic areas like grooming/boarding facilities or dog parks. Canine influenza is contagious and can spread between dogs from dog-to-dog interactions or through contact with contaminated surfaces. Fortunately, a vaccine is available to help protect at-risk dogs; Canine Bivalent Influenza Vaccine is administered through subcutaneous injection, and is initially given in a two-part series, then boosted annually as needed. The vaccination can be administered to puppies as young as eight weeks of age.
