Core Dog Vaccines 2023 Protocols—If You’re Revaccinating More Frequently Than Every 5-7 Years, You’re Probably Vaccinating Too Often

puppy getting dog vaccinesA lot has changed when it comes to dog vaccine protocols—from automatically vaccinating yearly to giving initial vaccinations and then titering. So, what’s a responsible dog person to do?

If you go to the American Animal Hospital Association or the American Veterinary Medical Association websites and search for core vaccines, you’ll find that the core vaccines—distemper, hepatitis, parvo, and rabies—should be given no more often than every 3 to 5 years. It’s really more like 5 to 7 years.

Veterinarians who insist on yearly dog vaccines for the core vaccines are out of touch. Worse, they are not even following the rules of their own association, the American Veterinary Medical Association. If you have such a vet, perhaps it’s time to start looking for a new vet who is up to date. And if you’re in the market for a holistic vet, this map will help you find one near you.


Age Range Vaccines/Titers Notes
*9-10 weeks Initial core DAP vaccines
(distemper, adenovirus, parvovirus)
If maternal immunity is
unknown and the puppy is
in a high-risk environment
*14-16 weeks Second round of core DAP vaccines Some puppies require a 3rd
round at ~18-20 weeks
based on environmental
4 weeks after second
round of core vaccines
Titer to verify immunization,
not just vaccinated
Titers are an antibody test
to help determine immunity
6-12 months Rabies As required by law
1 year Titer to verify immunized and
only vaccinate if needed
Before automatically
revaccinating, titer first.
Continue rabies as required
by law

*If puppies were kept in a safe environment and had good maternal protection (based on having a mother with good titers before breeding), our preference for our personal pets is to wait until 16 to 18 weeks to give the parvovirus vaccine, then distemper and adenovirus 2-3 weeks after that.

My dogs do get the core vaccines, and then I titer at 3 and 5 years. I am not against vaccines, but there is no benefit to over-vaccinating, while there are potential health risks.

Non-core Vaccines

With non-core vaccines (eg bordetella, Lyme, lepto, and canine influenza), each of us need to individually assess the likely exposure and risk of getting such diseases based on where we live and where we take our dogs. Because ticks and tick-borne diseases are rampant where I live, those are a no-brainer for me. You should check with your veterinarian to determine the best vaccine protocol for your individual pet.

Affordable Titer Tests

According to AAHA (American Animal Hospital Association): “Measuring antibody levels (quantitative or qualitative) provides a reasonable assessment of protective immunity against CDV, CPV, and CAV2.” A titer test can help determine antibody levels from a blood draw at your vet clinic. This is a test that can help assess a dog’s protection from diseases (eg distemper, adenovirus), by verifying if the dog has been immunized and not just vaccinated. And titer tests can help when you don’t know a dog’s vaccination history.

If you think you might like to try titering instead of automatically revaccinating, here are a few affordable places. Your vet will also have their own resources for this service as well.
