Routine vaccinations protect our pets from deadly infectious diseases by stimulating their immune system to fight off viruses. There are different types of vaccines available. Core vaccines are given to all pets, while other vaccines may be administered to a pet depending on their level of contact with sources of infectious disease. We recommend that both dogs and cats begin their schedule of vaccinations at about 8 weeks of age. In most cases, adult pets will receive annual vaccinations to maintain their immunity; certain vaccines may need to be administered semiannually, though. Read our blog post on vaccines for more information on why you should vaccinate your dog or cat.
