Overview
Colitis is inflammation of the large intestine (colon), causing frequent, urgent, often mucus-covered or bloody diarrhea. It can be acute (from dietary indiscretion or stress) or chronic (from IBD, food allergies, or parasites). Unlike small intestine diarrhea, colitis produces small, frequent stools with straining.
Symptoms to Watch For
- Frequent urgent diarrhea with mucus or blood
- Straining to defecate
- Small, frequent stools rather than large volumes
- Flatulence and abdominal discomfort
- Normal appetite in most cases
How Nutrition Helps
Highly digestible diets with added soluble fiber (psyllium, pumpkin) soothe the inflamed colon and feed beneficial gut bacteria. Novel protein or hydrolyzed diets help if food allergy is the trigger. Probiotics restore healthy gut flora. Avoiding high-fat foods reduces colonic irritation.
How Activity Helps
Stress is a major trigger for colitis in dogs. Regular, consistent exercise reduces stress and supports healthy gut motility. Avoid sudden changes in routine.
Prevention Tips
- Avoid sudden diet changes — transition over 7-10 days
- Add pumpkin or psyllium fiber to meals
- Keep stress levels low with routine
- Prevent scavenging and garbage eating
- Consider probiotics for recurring episodes
Breeds at Higher Risk
