Dog Diarrhea: 8 Safe Home Remedies (and 2 That Are Dangerous)
Vet-reviewed by Veterinary Reviewer, DVM · Last reviewed June 2026
For mild diarrhea in an otherwise healthy adult dog, safe home steps include a bland diet of boiled chicken and white rice, plain canned pumpkin, dog-specific probiotics, and plenty of water. Avoid giving human anti-diarrheal medicines like Imodium and Pepto-Bismol without veterinary guidance — they can be dangerous for some dogs. See a vet if diarrhea lasts beyond 48 hours or comes with blood, vomiting, or lethargy.
8 safe home remedies for mild dog diarrhea
- Bland diet — boiled, skinless chicken with plain white rice (about two parts chicken to one part rice), in small frequent meals, helps settle the gut.
- Plain canned pumpkin — 100% pumpkin, not pie filling. Its soluble fiber helps firm stool (roughly 1 teaspoon to 1 tablespoon depending on the dog’s size).
- Dog-specific probiotics — restore healthy gut bacteria; vet-recommended brands are best.
- Plain yogurt with active cultures — a small amount may help dogs that tolerate dairy; skip it if it worsens symptoms.
- Hydration — fresh water at all times; plain bone broth can encourage a reluctant drinker.
- A short rest for the gut — a brief fast (only for healthy adult dogs, with water always available) can help; never fast puppies, seniors, or pregnant, diabetic, or ill dogs.
- Easily digestible alternatives — boiled plain potato or lean ground turkey if chicken is not tolerated.
- A vet-recommended gastrointestinal diet — formulated sensitive-stomach foods are gentle and reliable for recovery.
The 2 remedies that can be dangerous
- Imodium (loperamide). It can be unsafe for dogs and is especially risky for herding breeds — Collies, Shelties, Australian Shepherds and others with the MDR1 gene mutation can have severe reactions. It can also mask a serious underlying problem. Use only if your vet specifically directs it.
- Pepto-Bismol / Kaopectate (bismuth subsalicylate). This belongs to the aspirin family, can irritate the gut, may cause black stools that hide signs of internal bleeding, and is toxic to cats. Do not give it unless your vet prescribes a dose.
When should I take my dog to the vet?
Get veterinary care if you see any of the following:
- Blood in the stool or black, tarry stool
- Repeated vomiting alongside diarrhea
- Lethargy, weakness, or signs of dehydration
- Refusal to eat or drink
- Diarrhea lasting more than 48 hours (sooner for puppies and seniors)
