Dosage: Recommended for the vaccination of healthy dogs 42 days of age or older. Shake well. Aseptically rehydrate vaccine with diluent supplied. Inject 1 dose (1 ml) subcutaneously into dogs that are at least 42 days old. Because there is potential for maternal antibody to interfere with the immune response, revaccinate every 14 to 28 days until the dog is 16 weeks of age. Dogs over 16 weeks of age should receive a single dose (1 ml). Annual revaccination with one dose is recommended. Warnings: Contains gentamicin as a preservative. Vaccinate only healthy, non-parasitized dogs. Do not vaccinate pregnant bitches. In case of anaphylaxis: administer epinephrine, corticosteroids, and/or antihistamines.
