How to firm up my puppy's soft, watery, gassy stools after parvo?

Updated On September 23rd, 2025

Pet's info: Dog | Siberian Husky | Female | unspayed | 5 months and 16 days old | 24 lbs

Luna has had soft stools and watery gassy bowel movements at night. She just survived the parvovirus about 2 1/2 weeks ago and has been eating her normal wellness core puppy food that was on before she got sick. Her stools seemed to firm up yesterday then became soft and watery at night and throughout today. She also had this issue before she got sick and the vet gave us pectalin, metronidazole, and Hills i/d and she still had soft stools. What should I do to help firm up her stools?

This could still be from the parvo. Puppies can have abnormal stool on and off for up to a month after surviving the disease. If that’s not the case, often a prescription strength high fiber or hydrolyzed protein diet will help. There are some cases that will not respond to diet, and at that point your vet can discuss referral to an internist, further testing, or medications like Tylan powder to help. Best of luck to you and Luna!

    Hello, sorry to hear about Axel. Other symptoms of Parvo include vomiting, decreased appetite, and lethargy. If he doesnt have these its very unlikely that he has parvo. Additionally, if he has been vaccinated already, then it is also less likely for him to get parvo. To fully rule this out he would need to be tested for parvo. More likely, the change in his diet is what is causing his soft stools. These should clear up within the next 3-5 days. Another possibility is that Axel has obtained some kind of parasite, in which its unlikely that his soft stools will resolve on their own. If Axel is not doing better in a few days, or if he is doing worse, then he should be seen by a veterinarian to have him tested for parvo and for other parasites. Best of luck and hope this helps!

    Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Archer! I would retest the stool for worms. If he had a large intestinal parasite load they might not be gone. Also his intestines went through a lot with the parvo. I would have him on a prescription intestinal diet like Hill's i/d or Royal Canin GI puppy for a few weeks to months. I would also put him on a probiotic like Purina Fortiflora. I wouldn't say it is normal for him to still have abnormal stool. Since he as recovered from parvo his stool should be normal, so something else is going on. I wish you and Archer the best!

    I am sorry to hear about Ruby. If she is active and eating and drinking normally with no vomiting, I would recommend dropping a stool sample off at your vet's office to check for intestinal parasites like worms, giardia and coccidia as these are all common in puppies and can cause diarrhea. The vet may want to go ahead and deworm the puppy to be safe. I would also consider starting a probiotic such as Purina FortiFlora which can help replenish the natural healthy bacteria found in the GI tract which can sometimes be lost due to disease.
