How Often Do Dogs Need the Parvo Vaccine?

The Parvo vaccine helps to protect dogs against canine parvovirus which can cause severe gastrointestinal illness.

In general, the series consists of 3 or 4 doses given every 2 to 4 weeks until the puppy is approximately 16 to 20 weeks of age. Depending on your area's prevalence of Parvovirus you may need to get a boost 1 year later. After this, most veterinarians recommend giving a Parvo booster vaccine once every three years to maintain immunity. Your vet will recommend the best vaccines based on your pup's lifestyle and risk of exposure.
