If you're worried, maybe find a holistic vet in your area, as they are equally qualified vets who normally only push necessary vaccines. Our dogs got the initial vaccines when they were pups and we did not live in an area with a holistic vet, but once we moved to Oregon, we found a good one. Our dogs get the 3-year rabies now and that's it. I'm not a fan of putting (usually unnecessary) chemicals into my body, or my dogs bodies, if I can avoid it. Good luck!
