Can my vaccinated dog get parvo after exposure to an infected dog?

Updated on September 23rd, 2025

Pet's info: Dog | German Shepherd | Male | neutered | 100 lbs

Can a fully vaccinated dog get parvo? My cousin recently moved and her dog Bella contracted parvo. Unfortunately Bella passed a few days ago. Bella wasn't vaccinated but their second dog King is fully vaccinated but they are worried he can get it too. King hasn't been living with them but today the family member he was staying with couldn't keep him anymore and decided to drop him off. Will King be ok or could he still get parvo?

Hello, parvo is generally a disease of young unvaccinated dogs and older dogs whom are vaccinated very rarely contract the disease. You should clean his environment daily with a dilute bleach solution to reduce the contamination of parvo, especially where Bella used to sleep and places where she may have had diarrhea. Ideally, keep King away from those areas at least until you have cleaned them. If King does contract parvo, which again is highly unlikely, he is most likely to have a very mild form of it due to his vaccinations. Monitor him for any vomiting, diarrhea, or a decreased appetite and have him evaluated by your veterinarian if you do not any of these. Hope this helps and best of luck.
