Just like humans, dogs need fiber in their diets to support healthy digestion, regulate weight, and maintain overall well-being. Whether you’re dealing with a pup prone to constipation, a senior dog with sensitive digestion, or simply looking to optimize your pet’s nutrition, high fiber dog food can make a meaningful difference. In this guide, we’ll explore the best high fiber dog food options available today, covering choices for weight management, allergies, sensitive stomachs, and more, so you can find the right formula tailored to your dog’s specific needs.
The Best High Fiber Dog Food According to Science
The best high-fiber dog foods are those that combine multiple plant-based fiber sources, are nutritionally balanced, and have demonstrated benefits in clinical studies.
These are the best high-fiber foods according to the latest research:
The top features of effective high fiber dog foods include:
Blend of fiber sources: Diets containing a mix of fibers from sources like beet pulp, flaxseed, citrus pulp, pecan shells, cranberries, pumpkin, psyllium, and cellulose show the greatest benefits for gut health, stool quality, and delivery of beneficial plant compounds.[1],[2],[3],[4]
Improved stool quality: High-fiber diets consistently improve stool firmness and regularity, both in healthy dogs and those with digestive issues or diarrhea.[5]
Gut health and metabolites: These foods increase beneficial short-chain fatty acids, reduce harmful metabolites, and deliver antioxidant and anti-inflammatory plant polyphenols to the gut.
Weight management: High-fiber foods are more effective for weight loss than high-protein/high-fat foods, and can help reduce fat mass while maintaining satiety and minimizing lean mass loss.[6],[7],[8]

Always consult your veterinarian before switching to a high fiber dog food.

Additionally, at-home dog gut health tests can provide insights into your dog’s microbiome, revealing whether added fiber could support better digestion. At-home food allergy tests may also identify ingredients to avoid, helping you choose a high fiber food that’s both safe and beneficial for your dog’s specific sensitivities.
