My puppy has recurring diarrhea, even after diet change and negative test.

Updated On September 23rd, 2025

Pet's info: Dog | Havanese | Male | neutered | 6 months and 11 days old | 11 lbs

My puppy has had diarrhea for the last 3 weeks, off and on. One day he will have formed, soft stools and the next he will have diarrhea. His diet has been switched to chicken, rice, and sweet potato instead of his dog food. A fecal test was done 1.5 weeks ago and it came back negative.

I would talk to your veterinarian about switching Sullivan to a prescription bland diet for a few weeks. I would also discuss medication that should help with the diarrhea. Just because a fecal test comes back negative does not mean there are no parasites. Parasites are not consistent shedders so checking a fecal sample again in a few days may help. Also, you should discuss just a general dewormer with your veterinarian just in case. Thank you for using Petco Pet Education Center, formerly Petcoach.
