Whether your dog has diarrhea but is acting fine, or you’re worried about more serious symptoms, knowing what to do next can make all the difference. This guide covers everything you need to know: from safe home remedies and what to feed a dog with diarrhea, to emergency warning signs and how to prevent future episodes. If your dog has diarrhea, you’re not alone—and with the right information, you can help your pup recover quickly and safely.
What to Do If Your Dog Has Diarrhea
If your dog has mild diarrhea but is otherwise acting normal, start with a short fast (6–12 hours), then feed small meals of plain boiled chicken and white rice. Offer plenty of water and monitor closely. If symptoms worsen or last more than 2–3 days, or if your dog is a puppy, senior, or has other health issues, call your veterinarian.

Common Causes of Diarrhea in Dogs
Diarrhea in dogs can be triggered by many things. The most common cause is dietary indiscretion—dogs eating garbage, table scraps, spoiled food, or foreign objects. Even a sudden change in dog food can upset their digestive tract. Other causes include:
- Bacterial infections: Salmonella, E. coli, Campylobacter
- Viral infections: Parvovirus, distemper (especially dangerous for puppies)
- Parasites: Giardia, coccidia, roundworms, hookworms, whipworms
- Stress and anxiety: Moving, boarding, loud noises, or new environments can cause “stress colitis.”
- Food allergies or intolerances: Sometimes with skin issues
- Inflammatory bowel disease (IBD): Chronic GI signs lasting 3+ weeks
- Medications: Antibiotics, NSAIDs, some heartworm preventives
- Underlying medical conditions: Pancreatitis, liver disease, Addison’s disease, cancer
For more on causes, see AKC’s guide to dog diarrhea.

Safe Home Care Steps for Dog Diarrhea
For mild cases in healthy adult dogs, home care can help your dog recover quickly:
- Short Fast: Withhold food for 6–12 hours (not for puppies, seniors, or dogs with health issues—consult your vet first). Always provide fresh water.
- Bland Diet: After fasting, feed plain boiled chicken (no skin or bones) and white rice in equal parts. Serve small, frequent meals.
- Plain Pumpkin: Add 1–4 tablespoons of plain canned pumpkin (not pie filling) to meals for extra fiber.
- Hydration: Encourage drinking. Offer ice chips or low-sodium, unseasoned bone broth if needed.
- Probiotics: Veterinary probiotics can help restore healthy gut bacteria. See the best probiotics for dog gut health.
- Rest and Monitor: Keep your dog calm and comfortable. Take them outside often and monitor stool changes.
- Gradual Return to Regular Diet: Once stools are firm for 24–48 hours, slowly mix in your dog’s regular food over 3–5 days.

OTC Medications: Imodium, Pepto-Bismol, and Other Options—What’s Safe?
Never give your dog human medications like Imodium or Pepto-Bismol without veterinary approval. Some breeds are especially sensitive, and these drugs can be dangerous or mask serious conditions.
- Imodium (loperamide): Not FDA-approved for dogs. Dangerous for Collies, Shelties, Australian Shepherds, and mixes with the MDR1 gene. Can worsen infections or cause side effects. Only use if your vet specifically instructs you.
- Pepto-Bismol (bismuth subsalicylate): Contains aspirin-like compounds. Can be toxic, especially with repeated dosing or in dogs with bleeding disorders, liver disease, or on other meds. Only use under vet guidance.
- Other OTCs: Kaolin-pectin products may help but are not proven and should only be used with vet advice.
Never give any human medication for diarrhea in dogs unless your vet tells you to. Diarrhea can be a sign of a serious infection that anti-diarrheal drugs should not suppress.
