Diarrhoea in dogs

Quick answer

For mild diarrhoea 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 diarrhoea lasts beyond 48 hours or comes with blood, vomiting, or lethargy.

Key takeaways

  • Mild cases often improve within 24–48 hours on a bland diet. If diarrhoea persists beyond 48 hours, see a vet.
  • Only under direct veterinary guidance. It can be unsafe for certain dogs, especially herding breeds with the MDR1 gene mutation.
  • Roughly 1 teaspoon for small dogs up to 1–2 tablespoons for large dogs per meal, using plain 100% canned pumpkin — not pie filling.
