Feeding your dog a high-fiber diet does more than just bulk up their meals—it supports health in multiple ways:

• Improved Digestion & Regularity
  Soluble fiber ferments in the colon to produce beneficial fatty acids, while insoluble fiber helps regulate bowel movement—the perfect combo to tackle both constipation and diarrhea. American Kennel Club

• Weight Management
  Fiber keeps your dog feeling full with fewer calories. This is especially helpful for overweight dogs where reducing food intake can be challenging. American Kennel Club

• Blood Sugar Control
  High-fiber diets slow digestion, helping regulate blood sugar—beneficial for diabetic dogs. American Kennel Club

• Digestive Health Support
  Fiber feeds beneficial gut bacteria, contributing to a healthy microbiome and reducing the risk of colon issues. American Kennel Club
