My adopted dog has diarrhea that won't stop. What tests are needed?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | unneutered | 15 lbs

So my dogs breed is lab/basenji. I adopted him from a shelter on februaury 10th he’s had diaherra every since we brought him home. Took him to the vet last month they did fecal examine and gave me diaherra pills. I used pumpkin sauce for a while it stopped working and now the diaherra pills don’t help. He is known to eating non food items. I Have a palm tree in my back yard that produces orange seeds and he’ll eat them but I believe they usually pas Been giving him rice and chicken for two days.

Thank you for submitting your question regarding your dog. Ongoing diarrhea can be very frustrating. I would recommend a diarrhea panel submitted to a reference laboratory to look for evidence an intestinal infection. This will be more detailed than testing performed at your local veterinary clinic. Next, I would recommend blood work and a urine sample to look for an underlying disease contributing to his symptoms. If no abnormalities are found on all of these tests, then I will usually implement a diet change. I hope this information helps!

    I hate to hear this is happening to Doug. It sounds like your veterinarian is working hard to figure out whats wrong. Since I don't know what tests have been run other than a barium study, you may want to discuss the following tests with your vet: Giardia Fecal Culture Pancreatic Lipase Insufficiency Food trial with 100% hydrolyzed Protein diet Food trial with high fiber food (Like Royal Canin Fiber Response or similar diet) Blood work to look at liver or kidney values 5 day trial of Panacur 6 week trial of Tylosin Referral to specialist I hope this helps an please feel free to post any additional questions.

    I'm sorry to hear that Daisy is having so much trouble! Chronic diarrhea can be a very frustrating problem. It sounds like she doesn't have a specific diagnosis yet, so I would be interested to know exactly what testing has been done and what treatments have been tried so far - feel free to request a consultation if you want to discuss things in more detail. In general, some tests that may be helpful in diagnosing the cause of chronic diarrhea like this would include a fecal analysis for parasites (including less common ones like Giardia and cryprosporidium), general blood work to check for a systemic illness that may be causing the diarrhea, a GI blood panel to look at whether or not nutrients are being absorbed appropriately, and even endoscopy or exploratory surgery with biopsies in some cases to check for things like IBD (inflammatory bowel disease) or GI lymphoma. If a full diagnostic work-up is not an option financially, then some treatment options that could be tried would include a diet trial with a prescription hypoallergenic or GI diet, metronidazole, an oral steroid like prednisone, and vitamin B12 supplementation. I would recommend taking Daisy back to one of the vets who has seen her before to discuss options for where to go from here, or asking for referral to an internal medicine specialist if you prefer.

    Poor Lola. There are so additional things that your vet could look into. I would have her poop tested for campylobacter and giardia. These are common parasites/bacteria that cause diarrhea but can be difficult to diagnose on a regular fecal test done in house. I would also try her on a prescription hypoallergenic food. If she has an allergy to something in the food, this could also cause on/off diarrhea. Finally, I would talk to your vet about running a GI panel. This tests for Vitamin B12, folate, and 2 pancreatic enzymes. I would also start her on a probiotic. I like Purina fortiflora, propectalin, or vetriscience brands. It is NOT normal for them to have diarrhea especially with blood this often. It could be stressed but I would want to rule everything else out. I hope this helps!
