Most adult dogs that were appropriately vaccinated against parvo as puppies - meaning 3 different vaccinations, given no earlier than 8 weeks of age and proceeding at 3 - 4 week intervals - are protected against contracting parvovirus, as long as they receive booster vaccinations as recommended. Typically, the recommendation is one vaccination on the one year anniversary of the last puppy vaccination, and then re-vaccination every 3 years after. Just one parvo vaccination is unlikely to be completely effective, but it may provide some protection, and if he contracts the disease it will likely be a milder form.
