My dog has diarrhea for a week. Should I withhold food or give meds?

It would be best to consult with your veterinarian before changing treatment or giving other medications. Legally, we are prohibited from recommending medications or dosing information in the absence of a physical exam and a patient-veterinarian-client relationship. You can try withholding food for 24 hours. Allow small amounts of water or an unflavored electrolyte replacement beverage. Resume feeding a bland diet in small frequent amounts until symptoms resolve. Transition slowly to the regular diet afterwards. A stool sample should be submitted to diagnose intestinal parasites or bacterial overgrowth. A veterinary probiotic such as Prostora, FortiFlora or ProViable may promote gut health.

Hello, if it was infectious, depending on the virus or parasite, you can get an incubation period which may delay the onset of clinical signs. Additionally, the events may be unrelated. That is, Pepper could be having its own cause for the diarrhea. In terms of the metronidazole, Bella is safe to continue to receive it if your veterinarian deems so necessary. You could use a bland diet (plain white rice, boiled skinless and boneless chicken, and low fat cottage cheese) for 3-5 days to see if this helps their clinical signs resolve. If not, then you should have your veterinarian evaluate them immediately. Hope this helps and best of luck.

Some dogs that have an underlying disease like inflammatory bowel disease do need long term antibiotic use, but it is best to have a diagnosis before continuing medications long term for two reasons: one is that antibiotic usage can sometimes mask the underlying problem, and the other is that there can be effects on the gastrointestinal flora. There are many diseases that could cause chronic diarrhea including a food intolerance, pancreatitis, or inflammatory bowel disease as stated above. I would recommend talking to your veterinarian to see if other tests or treatments are recommended at this point to try to diagnose the problem - some additional tests might include a pancreatic lipase test, cobalamin/folate, abdominal ultrasound or even obtaining intestinal biopsy samples to try to determine what might be causing chronic diarrhea. You might also want to talk to your veterinarian about a hypoallergenic food trial.

It could be that the diarrhea worsening is independent of the metronidazole as this drug does not help all cases of diarrhea, dependent on the cause. But since it is new it would be best to stop until you can speak with your vet. Has your kitty had a work up for these symptoms? Chronic vomiting and diarrhea are common symptoms of several things, but most notably GI disease. It would be abnormal for a cat to need chronic medication for vomiting unless there is a disease process there. Just to help a little, a work up for an older kitty with these signs could include bloodwork with thyroid testing, an abdominal ultrasound, and sampling if needed (dependent on ultrasound). If there is an underlying disease that can be treated your kitty may feel better and need less medications eventually.

Hi! I would say that it is likely ok. Sometimes it takes a bit longer to see results. If it is just soft and Snowball is otherwise fine, I would just give it a few days before getting concerned. Keep in mind that metronidazole is not always a curative medication for diarrhea but rather an antibiotic with anti-inflammatory properties that help with colitis. This means that it will not treat an underlying disease every time. Perhaps try a few days on a bland diet mostly composed of boiled chicken or turkey and rice. If no resolution within a few days, it may be appropriate to start her on a probiotic or try a different medication such as Tylosin. Best of luck with her!

If your dog does not start showing improvement after 48 hours of being on the medication and/or if his symptoms persist, then you should take him back to your veterinarian for a recheck. He may need additional diagnostics like blood work, X-rays, and/or a parvo test (depending on his vaccination status). He may also need supportive care like nausea medication and fluid therapy. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

Hi there. In my experience, it often takes 48 hours or so to see improvement in diarrhea after starting metronidazole. Full resolution of the problem may take another 2-3 days from there. So if Jake's diarrhea seems to be improving and his appetite is better, this is a good sign. I would continue with the current treatment plan prescribed by your veterinarian. If his diarrhea has not resolved in another 2-3 days, then I would recommend taking him back in for a recheck to see if some other type of treatment is needed.
