My dog survived Parvo, was vaccinated. Now has diarrhea. Is it Parvo?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 55 lbs

Peaches had her live Parvo vaccine on June 27, 2018. She was a Parvo survivor also. Last Wednesday we had a rescue dog stay at our house overnight. He was diagnosed 2 days later with Parvo. She woke up this morning with diarrhea but with no blood. I am terrified she has taken Parvo again. Could this be Parvo?

Thank you for submitting your question regarding Peaches. It is highly unlikely that she has the parvovirus again. She will have immunity from her previous infection as well as the vaccine. There are numerous causes of diarrhea. I recommend that she sees her veterinarian for fecal testing. I hope this information helps!
