My puppy was exposed to parvo after her second vaccine. What to do?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | unspayed | 3 months and 12 days old | 21 lbs

My puppy had her second vaccination for parvo and she came in contact with another puppy who we have found out has parvo. Please let us know what we can do. She had her second vaccination Feb 1st and she is 3.5 months old. She is a street dog and we brought her in our house about two weeks ago but we had brought her to a vet around 2 months for her first round of vaccinations.

As long as Begum is current on her puppy vaccination series, meaning that she has had her booster shots on time, it's unlikely that she will develop parvo even if she has been exposed. The vaccine is normally very effective. That being said, there isn't anything you can do one way or the other at this point to influence whether she'll get sick or not. Just hope the vaccine has done its job! To be safe, I would monitor her closely for the next 10-14 days for any signs of parvo, including vomiting, bloody diarrhea, lethargy, or not wanting to eat. If you have any concerns, you should take her to the vet to start treatment right away.
