Canine Gastrointestinal High Fiber Dry Dog Food
Verified Jun 9, 2026
This is a high-fiber dry veterinary diet formulated for adult dogs who need extra digestive support and help maintaining a healthy body weight. It uses chicken by-product meal as the main protein source, with multiple fiber sources like pea fiber, powdered cellulose, beet pulp, and psyllium to help regulate intestinal transit. Added prebiotics and omega-3 fatty acids (EPA and DHA) support overall gut health and general well-being when used under veterinary guidance.
This is a well-designed therapeutic high-fiber diet for adult dogs that appears particularly suitable for those with certain chronic gastrointestinal issues when prescribed by a veterinarian. Protein and fat levels are moderate, and the formula provides a wide variety of soluble and insoluble fibers along with prebiotics and omega-3s to support digestive function. It’s complete and balanced for adult maintenance and is best used specifically for dogs who need a higher-fiber regimen rather than as a routine food for all dogs.

KibbleLab Review
Strengths
- Multiple complementary fiber sources (pea fiber, powdered cellulose, beet pulp, psyllium) provide a robust high-fiber profile that can help regulate stool quality and intestinal transit in dogs that need this approach.
- Chicken by-product meal as the primary protein source offers a nutrient-dense, highly usable animal protein rather than relying heavily on plant proteins alone.
- Includes prebiotic fructooligosaccharides and selected highly digestible proteins, which can support a healthy gut microbiome and better nutrient absorption.
- Added omega-3 fatty acids from fish oil and marine microalgae oil, plus antioxidants like vitamins C and E, support overall health and may be beneficial for dogs with chronic GI issues.
Considerations
- This is a specialized high-fiber prescription diet and may not be ideal for healthy dogs without a medical reason, as the fiber level is significantly higher than in standard maintenance diets.
- Contains common allergen sources such as chicken, wheat, corn, and fish, so it would not be appropriate for dogs with known sensitivities to any of these ingredients.
- The diet is formulated for adult maintenance only and is not suitable for growing puppies or pregnant/lactating dogs.

Top 5 Ingredients Explained
01
Chicken By-Product
Chicken by-product is a common protein ingredient in pet foods made from edible parts of the bird not typically consumed by people—such as organs (liver, heart), necks and other tissues—and is used to add protein, flavor and nutrient density. It can provide concentrated protein, essential amino acids, B vitamins and minerals (and may contribute taurine when organ meats are included), but composition and quality vary by source, so pet parents concerned about sourcing, higher ash/fat content or chicken allergies should check the manufacturer’s labeling and quality standards.
02
Brewer's Rice
Brewer’s rice is a milling byproduct of rice processing made up of small broken white rice kernels commonly used in pet foods as a highly digestible carbohydrate source, filler and binder that provides readily available energy for dogs and cats while contributing little protein, fat or fiber. It is generally gentle on the stomach and cost‑effective, but diets using it must supply other ingredients for essential nutrients; pet owners should note its relatively high glycemic load (relevant for weight or diabetic pets), the potential for trace environmental contaminants associated with rice, and not confuse it with brewer’s yeast.
03
Pea Fiber
Pea fiber is an insoluble plant fiber derived from peas commonly used in pet foods as a source of dietary fiber and as a texturizer/binder to help form kibble, increase stool bulk, and reduce calorie density; it provides little protein, fat, vitamins, or minerals but can aid satiety and regularity in dogs and cats. While pea fiber can support digestive health and weight management, it may cause gas or looser stools in some pets and — because pea-derived ingredients have been discussed in the context of concerns about grain‑free diets and canine dilated cardiomyopathy — it should be used as part of a balanced, veterinarian‑approved formulation rather than in excessive amounts.
04
Chicken Fat
Chicken fat is used in dog and cat foods as a concentrated energy and flavor source that supplies essential fatty acids (notably linoleic acid) and aids absorption of fat‑soluble vitamins, improving palatability and supporting skin and coat health. Because it is calorie‑dense, diets must account for added fat to prevent weight gain, and quality (proper rendering and antioxidant protection to prevent rancidity) is important; although fats are less commonly allergenic than proteins, pets with poultry sensitivities may still react in some cases.
05
Wheat
Wheat is a common cereal grain used in pet foods as a source of digestible carbohydrates, some plant-based protein, B vitamins, minerals, and dietary fiber, and it also helps with kibble texture and binding. It provides energy and fiber for many dogs but can cause food allergies or gluten sensitivities in a minority of pets and is generally less ideal as a primary ingredient for obligate carnivores like cats, so pets with known grain or wheat sensitivities should avoid it and calorie intake should be monitored to prevent weight gain.
