When Can I Vaccinate My Dog After Parvo?

Vaccinate for Parvo Again in 3 Weeks

If this were my dog, I would also want to vaccinate her for Parvo again in about 3 weeks after that first injection, just to make sure that her immune system was strong enough to make antibodies. She will not need to be vaccinated again until 3 years after that.
