Why is my parvo dog still weak, vomiting blood after 2 days?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | unspayed | 3 months and 4 days old | 13 lbs

This is my dog’s poop after 2 days of medication. She is positive in parvo. Her vet already gave her antibiotics, but still no improvement. She still vomits and poop blood. She is very week.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Berry!

Parvo is a very serious disease and sadly can take much longer than 2 days to resolve. On average it takes 3-7 days and the puppies get worse before they get better. That is a lot of diarrhea. Be sure that you are keeping up with Berry's hydrational needs. Hopefully she is getting IV fluids, IV antibiotics and IV antinausea medications since she isn't holding anything down. Ideally she should be hospitalized if that is possible.

I hope this helps and I wish Berry the very best!
