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.
Rabies shots are one of the vaccines you will need to get your new puppy. These shots can be given to puppies that are 16 weeks of age. You will also need to get a vaccine booster when your puppy is a year old. Additional boosters need to be given every three years after the first two Rabies vaccines.
