My puppy is home after Parvo. Can he get sick again? What symptoms?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | neutered | 2 months and 19 days old | 17 lbs

My puppy was sent home today (yay!!!) from the vet after battling Parvo. We were given 3 medications for him to take every 12 hours. Is there any possibility he could regress? Or since we were sent home we are out of the woods? If regression is possible, what symptoms should I look out for?

I’m glad to hear that your Jasper is back home! Parvo can be tricky, and Jasper will need to be monitored carefully for any returning signs of illness. If you notice any vomiting, diarrhea, decrease in appetite, decrease in energy, or blood in the stool, please contact your vet right away. Please see the following link from the American Veterinary Medical Association's website for more information on parvovirus https://www.avma.org/public/PetCare/Pages/canine-parvovirus.aspx . Good luck with your boy!

    It depends on how sick he was and how long he was hospitalized. Typically a parvo case will take 3-7 days to improve and once they start eating well enough to transition to oral medicines they are considered out of the woods and continue to improve. If you notice any vomiting or diarrhea then I would be concerned.
