My puppy had Parvo. Why is he still vomiting and has diarrhea?

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. In dogs infected with parvo virus, there can be long term health effects from the infection such as chronic gastrointestinal disease. I would recommend going on a sensitive stomach formula and adding in a probiotic to see if this helps. As always, check the stool for intestinal parasites to make sure a parasite is not the cause. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Thanks for using Petco Pet Education Center, formerly Petcoach! Parvovirus is a severe gastroenteritis that affect puppies more often. This is a viral infection so there is no direct treatment for the virus so the treatment per se is directed at treating secondary bacterial infections and mostly helping with the clinical symptoms of vomiting, diarrhea and inappetence. This warrants ideally hospitalization with some cases being able to be managed with outpatient care depending on its severity. I recommend that you follow up with a veterinarian who can institute therapy for Loki as soon as possible. The quicker this condition gets treated the better the outcome tends to be. Good luck! Hoping for a quick recovery!  

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. I'm sorry to hear that Luna has parvovirus but I'm happy to hear you are getting her treatment. Your veterinarian may have recommended to hold off food for a little bit to reduce the risk of her vomiting it back up. I would contact them to clarify the timeline that they recommended these things. Generally, withholding food for 8-12 hours is sufficient. Also, we do not generally recommend preventing dogs from drinking water. I would allow her access to water, and call your veterinarian to have them clarify why and for how long they don't want Luna to have food. I hope this is helpful!

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!

Most pets will begin showing signs of recovery after 4-5 days of starting treatment. It sounds like Celie is still not doing as well as expected and that is concerning. I recommend to have her examined again. Have her bloodwork checked to see if she is struggling with low blood protein levels or low platelet numbers. Some pets may need additional colloid fluids or a plasma transfusion. Your veterinarian may also need to do an x-ray to see if there is something else going on like an intestinal blockage. Celie should also be eating a bland diet. I recommend one of the prescription diets like Hill's i/d or Royal Canin gastrointestinal. She may need to be force fed (but only do so with your veterinarian's approval). If you do continue to feed her baby food, make sure there are no onions or garlic in the ingredients. If you cannot get food into her easily, she may need a feeding tube placed or other form of parenternal nutrition. It sounds like you are trying very hard. I can't say if she should be examined tonight or not since I can't examine her and don't know what condition she is in. If she is declining though, she should be examined tonight for sure. Definitely have her checked first thing tomorrow morning if she does not go in tonight. I hope this helps and that Celie starts to recover as expected.

Hello. This is very, very unusual. Once a parvo patient recovers, they continue to do well. And, I have never heard of a pup recovering from parvo needing medication for 3 weeks. If Chico had parvo 3 weeks ago, & just started vomiting 4 days ago, it has nothing to do with his previous illness. Something else is going on. Please contact your veterinarian, as he may need to modify whatever medication he prescribed. I hope Chico is back to normal very soon & thanks for using Petco Pet Education Center, formerly Petcoach.

If Alexaander has been treated for parvovirus recently it is concerning that he is still vomiting. Sometimes dogs with parvovirus can develop an intussusception, which is a condition where the intestine folds in on itself causing an obstruction. This could cause diarrhea to stop while vomiting continues. Severe dehydration could also cause this. I would recommend a recheck with the vet who initially treated Alexaander: they may recommend some tests like an x-ray or additional treatment to control nausea and correct dehydration.
