Every decision in this recipe was made around two things: keeping phosphorus as low as possible, and keeping moisture as high as possible. White fish and egg whites provide high-quality, highly digestible protein with minimal phosphorus. Broth and courgette add moisture. No organ meat. No dairy. No bones.
Dogs with CKD should have their diet managed under veterinary guidance. Appropriate phosphorus restriction, protein levels and potassium management depend on the CKD stage (IRIS 1–4). This recipe provides a low-phosphorus framework — your vet may advise modifications based on your dog's specific bloodwork. Do not attempt to manage CKD through diet alone without veterinary involvement.
White fish fillet (cod, tilapia, pollock) and egg whites are among the lowest-phosphorus animal proteins while remaining high biological value — efficient protein that leaves less waste for impaired kidneys to process.
CKD dogs lose concentrating ability and are chronically at risk of dehydration. Broth and high-water vegetables maximise moisture intake with every meal — something dry kibble fundamentally cannot do.
Courgette, cabbage and carrots are among the most kidney-friendly vegetables — very low phosphorus, gentle on digestion, and provide vitamins without adding mineral burden.
White rice is one of the lowest-phosphorus carbohydrates available and is highly digestible. For CKD dogs, it's preferred over brown rice (which has slightly higher phosphorus from the bran layer).
EPA and DHA from salmon oil reduce inflammatory processes in kidney tissue that accelerate nephron destruction. Multiple studies show omega-3 supplementation slows the rate of CKD progression.
Zero organ meat. Zero dairy. Zero sardines with bones. Zero bone meal. These are the foods most likely to accelerate kidney damage in a CKD dog — all excluded entirely.
Select your dog's size. Portions are for one meal; most CKD dogs benefit from two smaller meals per day to reduce the protein waste load at any one time.

Place fish fillet in a pan. Cover with plain, unsalted water. Bring to a gentle simmer and cook 8–10 minutes until completely opaque and flakes easily. No salt, no oil. Remove from pan and let cool slightly, then flake into small pieces.
Scramble egg whites in a small non-stick pan with no fat and no salt. Cook until set. Egg yolk is omitted in this recipe because the yolk contains the majority of egg phosphorus — the white alone gives excellent quality protein with very low phosphorus.
⚠️ Egg yolk = high phosphorus. Use whites only for CKD dogs.Cook white rice until soft. Steam courgette and cabbage until completely tender — softer than al dente, so it's easy to digest. No salt at any stage.
Combine fish, egg whites, rice and vegetables. Pour unsalted broth over everything — this is the key moisture addition that makes this bowl more hydrating than a dry meal.
Cool to room temperature. Stir in salmon oil (never hot) and eggshell calcium. For advanced CKD dogs (IRIS Stage 3–4), discuss calcium supplementation with your vet — the calcium:phosphorus ratio management becomes more complex at later stages.
Several breeds have documented hereditary kidney conditions or simply higher incidence of age-related CKD. Knowing your breed's risk profile is helpful for deciding when to start regular kidney screening.
Beyond the broth in this bowl, multiple fresh water sources around the home, a pet water fountain, and occasional broth-flavoured water can all help a CKD dog stay hydrated. Dehydration in a CKD dog can precipitate acute kidney injury on top of chronic disease — hydration support is as important as the food itself.
