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.
Your puppy will need his first rabies shot when heâs about three to four months of age, something that usually is set by your county or town, rather than your vet. Heâll need a booster again in a year, and then once every one to three years after that.our vet will determine the exact schedule, but typically these booster shots are given every two to four weeks until the pup is about 16 weeks old. The reason for the boosters is that puppies normally get some immunity from their mothers, and this natural immunity actually prevents the shots from doing him any good.
