We learned of the latest updates to the AAHA Canine Vaccination Guidelines last September. One of the significant updates was to make the guidelines available online for the veterinary profession. With almost twice the content of the previous version, AAHA’s revised and updated Canine Vaccination Guidelines include important changes and new recommendations that are important for all practitioners.

Among the most significant updates in the guidelines is the recommendation for an optional 4th dose of a combination core vaccine (distemper-adenovirus 2-parvovirus ± parainfluenza virus) at 18 to 20 weeks of age. The 4th dose option is recommended for any practice experiencing confirmed parvovirus or distemper virus infections in young dogs despite having completed (by 16 weeks) a 3-dose initial series.
