Is my 6-month-old puppy protected from parvo after only two shots?

Updated On September 23rd, 2025

Pet's info: Dog | Anatolian Shepherd | Female | unspayed | 5 months and 22 days old

Hi, we are bringing home a new puppy in a couple of days. She is 6 months old and had 2 rounds of parvo shots at 6 and 9 weeks. Almost 2 years ago we had a dog on our property get sick from parvo so I'm worried about the new pup. Being 6 months old and having had 2 rounds of shots, is she protected from parvo?

Below are the recommendations for vaccines from the American Animal Hospital Association. According to these guidelines which are widely accepted, 1 more DHPP vaccine (distemper, hepatitis, Parvo, parainfluenza) should be sufficient; she will then need to have that repeated in a year. https://www.aaha.org/public_documents/guidelines/vaccination_recommendation_for_general_practice_table.pdf To clarify, Parvovirus CAN survive in the environment (soil, etc) for 6 months to 1 year or longer depending on conditions. (The longest time I could find cited was 2 years in the environment). I say that not to alarm you, but to clarify that some caution should be taken. Since its been nearly 2 years, it is unlikely that your house and yard are a source of parvo, and I do not think you need to do anything specific to disinfect or decontaminate. But DO get the puppy vaccinated. https://www.avma.org/public/PetCare/Pages/canine-parvovirus.aspx I hope that helps you! Best of luck with the new puppy.

    Unfortunately, if she only had two shots at 6 and 9 weeks she is not protected. She will need to start all over with vaccinations in order to be protected from parvo, distemper, infectious hepatitis, rabies, etc. The parvo virus in your property should be gone, the virus cannot live that long outside of the body. So she should be safe there provided no other sick dog was on it within the past three months. Best make an appointment for vaccinations and worming for next week.
