My dog has chronic diarrhea despite many vet visits. What can I do?

Updated On September 23rd, 2025

Pet's info: Dog | Pembroke Welsh Corgi | Female | spayed | 6 months and 6 days old | 25 lbs

Mía has soft poop or diarrhea almost every other day. We have been to the vet many of times and have even done fecal tests. I’m becoming very frustrated but I don’t know what to do about it anymore. One day she’s fine and the next it’s like water. She even had a grain free diet. I feel helpless. :(

It can be very frustrating to work up diarrhea! You might discuss emperical treatment for intestinal parasites and giardia with your vet (many times a pet can have giardia but it cannot be seen on every fecal exam). Food allergies aren't terribly common in puppies, but a grain-free diet isn't going to be the answer. It could be something in that diet that causes Mia to have diarrhea. You might discuss a hypoallergenic food or an easily digestible diet with your vet. Blood work and a GI panel may also be needed to look for any actual intestinal disease. Prescription probiotics are a great idea while we are working on diagnosis.
