A booster is a repeat of a previous vaccine that the dog has already received. The goal of the booster is to boost the dogs immunity up to an effective level. Older dogs need boosters every 1-3 years because otherwise their immunity would start to drop.
Vaccinations for Dogs. Routine vaccinations for dogs usually protect against Parvovirus, Hepatitis, Leptospirosis and Distemper. Many dogs receive these vaccinations as puppies and then further booster vaccinations throughout their lives. Some vaccinations need annual boosters others have a three-year life. You should check with your vet when your dog's boosters are due. If your dog has not been vaccinated before, then they cannot be boarded in kennels until 7-14 days after vaccination.
