descriptionOverview

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.

searchSymptoms to Watch For

  • warningFrequent urgent diarrhea with mucus or blood
  • warningStraining to defecate
  • warningSmall, frequent stools rather than large volumes
  • warningFlatulence and abdominal discomfort
  • warningNormal appetite in most cases

restaurantHow 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.

Stress is a major trigger for colitis in dogs. Regular, consistent exercise reduces stress and supports healthy gut motility. Avoid sudden changes in routine.
