Chronic or recurring diarrhea is frustrating for dogs and owners alike. While occasional loose stools are normal, persistent diarrhea may indicate the need for a dietary change to a more digestible, gut-supporting formula.
Understanding Diarrhea in Dogs
Diarrhea can range from a minor inconvenience to a serious health concern requiring veterinary attention.

Common Causes
- Dietary indiscretion (eating something they shouldn't)

Feeding Tips to Prevent Diarrhea
Dietary Management
- Feed consistent diet: Avoid frequent changes
- Transition slowly: 10-14 days for new foods
- Small, frequent meals: 3-4 meals daily
- Limit treats: Keep to 10% of calories
- Avoid table scraps: Common cause of upset
Environmental Factors
- Reduce stress around mealtimes
- Prevent garbage eating
- Keep feeding area clean
- Control access to other animals' food
Transitioning to New Food
For diarrhea-prone dogs, slow transitions are critical:
14-Day Transition
- Days 1-3: 90% old, 10% new
- Days 4-6: 75% old, 25% new
- Days 7-9: 50% old, 50% new
- Days 10-12: 25% old, 75% new
- Days 13-14: 100% new
If diarrhea occurs during transition, slow down even more.
Frequently Asked Questions
My dog has chronic diarrhea. Should I change food?
If diarrhea is persistent (beyond 48 hours), first consult your veterinarian to rule out underlying conditions. If food intolerance is suspected, a highly digestible or limited ingredient diet may help.
Can pumpkin help with diarrhea?
Plain canned pumpkin (not pie filling) can help firm stools due to its soluble fiber content. Add 1-2 tablespoons for small dogs, 2-4 for larger dogs. However, pumpkin treats the symptom, not the cause.
Should I give probiotics for diarrhea?
Probiotics can help restore healthy gut bacteria and may benefit dogs with diarrhea. Many digestive-support foods contain probiotics, or they can be supplemented separately. Consult your vet for recommendations.
Is bland diet (chicken and rice) good for chronic diarrhea?
Bland diets can help during acute episodes but aren't nutritionally complete for long-term feeding. For chronic issues, a digestive-support commercial diet is more appropriate.
