This is a therapeutic diet, formulated for a specific medical condition under veterinary direction. KibbleLab does not assign it a general wellness score, because a therapeutic diet's nutrient targets are set clinically, not by maintenance standards. Your veterinarian selects the right therapeutic diet for your pet.
At a Glance
Where these benefits come from
Benefits the manufacturer highlights in its own product marketing. KibbleLab lists them for reference and does not verify these claims.KibbleLab Review
Strengths
- Formulated and tested through AAFCO feeding trials as complete and balanced for adult maintenance, which is a strong level of evidence.
- Protein, phosphorus, and sodium are all restricted, which is appropriate for many dogs with chronic kidney disease.
- High omega-3 fatty acid level can be helpful for both kidney support and joint health in many dogs.
- Includes glucosamine, chondroitin, L-carnitine, and prebiotics to support joint comfort, body condition, and gut health.
Considerations
- The 16% protein on a dry-matter basis is lower than regular adult foods, so it’s really only suitable for dogs who need protein restriction.
- Main ingredients are brewers rice and chicken fat, so it may not be ideal for dogs who truly require a higher meat content diet.
- Contains chicken, egg, and fish, so it would not be appropriate for dogs with confirmed allergies to those ingredients.
- This is a prescription therapeutic diet and should only be used under guidance from your veterinarian.

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
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.
03
Flaxseed
Flaxseed is used in pet foods as a plant-based source of alpha‑linolenic acid (ALA) omega‑3, soluble and insoluble fiber, and modest protein, often added to support skin and coat condition, digestive health, and kibble texture; ground seed or flaxseed oil is more digestible than whole seed. Dogs can partially convert ALA to long‑chain EPA/DHA but cats convert ALA poorly and therefore still need marine sources for essential DHA/EPA; flax is calorie‑dense, prone to oxidation if not stabilized, and contains lignans (phytoestrogens) and trace cyanogenic compounds, so it should be processed and used in moderation.

04
Chicken
Chicken is a common animal-based protein in dog and cat foods, supplying essential amino acids, B vitamins, and energy-dense fats that support muscle maintenance, growth, and overall health; for cats it also contributes toward dietary taurine but must be present in sufficient amounts or provided via supplementation. It is prized for its digestibility and palatability, though some pets develop sensitivities or allergies to chicken, and nutritional value and safety depend on ingredient quality and processing—raw chicken carries pathogen risks and whole bones can pose choking or GI hazards.

05
Egg Product
Egg product is used in pet foods as a high-quality, highly digestible animal protein and palatability enhancer, providing complete essential amino acids, fats, vitamins (such as A, D and B12), minerals and choline, and it often serves as a binder or emulsifier when included as whole, dried or concentrated egg. It supplies bioavailable nutrients for dogs and cats but can be a food allergen for some individuals, may be higher in fat depending on yolk content, and should be properly processed (pasteurized or cooked) to reduce microbial risk.
