Please note: The term "9-way vaccine" refers to a 7-way vaccine that provides protection against four types of Leptospirosis rather than two. Recommended for vaccination against canine distemper, adenovirus cough, hepatitis, parainfluenza, parvovirus, and four types of leptospirosis. The parvovirus portion is modified live canine cell origin. Canine adenovirus-2 (CAV-2) helps provide protection against both canine infectious hepatitis and tracheobronchitis (kennel cough). Give subcutaneously or intramuscularly.
