Pro Plan Veterinary Diets EN Gastroenteric Low Fat Dry Dog Food
Verified Jun 15, 2026
This is a low-fat, highly digestible dry veterinary diet for adult dogs who have trouble digesting fat or need gastrointestinal support. It uses brewers rice and barley as the main carbohydrate sources, with corn protein meal and poultry by-product meal providing moderate protein, plus added prebiotic fiber (inulin) to support the gut microbiome. Antioxidant vitamins, including vitamins E and C, are included to help support overall immune and digestive health under your veterinarian’s guidance.
Nutritionally, this is a well-designed therapeutic GI formula for adult dogs that need a low-fat, easily digestible diet under veterinary supervision. Protein and fat levels are appropriate for many dogs with chronic digestive issues, and the use of prebiotic fiber and antioxidants supports gut and overall health. It’s best suited for dogs with specific gastrointestinal conditions rather than as a general everyday food for healthy dogs.

KibbleLab Review
Strengths
- Designed as a low-fat formula (about 5–9% fat as-fed; ~10–16% on a dry-matter basis), which can be helpful for dogs that don’t tolerate higher-fat diets or have certain GI issues.
- Moderate protein level (25% as-fed) from corn protein meal and poultry by-product meal, which can be highly digestible and provide essential amino acids when well processed.
- Contains inulin, a prebiotic fiber, to help support a healthy gut microbiome and digestive function.
- Complete and balanced for adult maintenance according to AAFCO nutrient profiles, with added antioxidant vitamins E and C for additional support.
Considerations
- Main protein sources are corn protein meal and poultry by-product meal rather than a named whole meat, which is fine nutritionally but may not suit dogs with chicken or corn allergies.
- Carbohydrates from brewers rice and barley make up a substantial part of the formula, which may not be ideal for very high-protein diet preferences or some dogs needing stricter carbohydrate control.
- This food is formulated for adult maintenance only and is not appropriate for growing puppies, especially large-breed puppies.
- As a veterinary therapeutic diet, it should be used only under the direction of a veterinarian, particularly if your dog’s condition or weight changes over time.

Top 5 Ingredients Explained
01
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.
02
Barley
Barley is a cereal grain used in pet foods primarily as a digestible carbohydrate and source of dietary fiber (including soluble beta‑glucans), along with modest amounts of B vitamins and minerals. It can support healthy digestion, help moderate post‑meal blood sugar and aid weight management in dogs, but provides limited protein for obligate carnivores like cats, must be cooked/processed for good digestibility, and may be unsuitable for pets with grain sensitivities or calorie‑restricted diets.
03
Corn Protein Meal
Corn protein meal is a concentrated plant-based protein ingredient commonly used to raise crude protein and energy in dry kibbles, treats and some wet diets as a cost-effective alternative to animal protein sources. It provides digestible amino acids for dogs but has an incomplete amino acid profile (notably low in lysine and lacking taurine), so it should be balanced with higher-quality animal proteins for growing animals and obligate‑carnivore cats; some pets may also be sensitive to corn and quality/sourcing can affect safety and nutrient content.
04
Poultry By-Product
Poultry by-product is used primarily as a concentrated protein, fat and micronutrient source in pet foods and consists of rendered poultry parts such as internal organs, bones and connective tissues that supply amino acids, minerals (notably calcium and phosphorus) and B‑vitamins. It can be a cost‑effective source of bioavailable nutrients, but composition and quality vary by source and processing—owners of pets with poultry allergies or who prefer named-meat ingredients may choose alternatives, and safety depends on reputable rendering and adherence to regulatory standards.
05
Animal Digest
Animal digest is a concentrated flavoring produced by enzymatic or chemical hydrolysis of animal tissues and is used in pet foods primarily to enhance palatability rather than serve as a primary protein or nutrient source. It contributes savory taste and small amounts of amino acids, but sources are often unspecified (which can be a concern for pets with protein sensitivities or owners seeking novel proteins), and it may contain elevated salt or purine levels, so check the label and consider dietary restrictions for pets with renal, hepatic, or allergy issues.
