The liver processes everything that enters the bloodstream from food. When it's under stress from disease or copper accumulation, what a dog eats matters enormously. This recipe keeps copper extremely low, provides highly digestible protein from white fish, and uses carbohydrates as the primary energy source to spare the liver from overworking.
Liver disease in dogs presents in many different forms — copper storage disease, chronic hepatitis, portosystemic shunts, hepatic lipidosis and others — and the dietary approach differs between them. This recipe provides a general low-copper, hepatic-supportive framework. Your vet's guidance on protein restriction, sodium management, and whether your dog needs a shunt-specific diet takes precedence over any generic recipe. Always use this recipe as a starting point under veterinary supervision, not as a standalone solution.
White fish is one of the lowest-copper animal proteins. Organ meats (liver, kidney) are eliminated entirely — they are among the highest copper foods and should be completely avoided in hepatic disease.
White rice provides glucose energy that the liver can store as glycogen without requiring metabolic conversion. This carbohydrate-forward approach reduces the liver's processing load.
Hepatic inflammation generates significant oxidative stress. Anthocyanins and polyphenols from blueberries provide direct antioxidant support to liver cells under stress.
Sulforaphane activates Nrf2 — the master antioxidant switch — and has shown hepatoprotective effects in multiple studies, supporting the liver's own detoxification pathways.
Both are low-copper, easily digestible, and provide beta-carotene. Their natural sweetness makes this recipe palatable for dogs with reduced appetite — common in liver disease.
Liver, kidney and heart are eliminated completely. These are the highest-copper foods in any diet and would directly worsen copper accumulation in affected breeds.
Select your dog's size. For dogs with hepatic encephalopathy (confusion, circling, seizures related to ammonia buildup), protein must be restricted further under veterinary guidance — these standard portions may need to be reduced.

Omega-3 fatty acids from salmon oil have anti-inflammatory effects that can benefit the inflamed liver, and several studies suggest EPA and DHA have hepatoprotective properties. However, in dogs with severe hepatic dysfunction, fat metabolism may be impaired. Keep salmon oil at the standard maintenance dose here — do not increase it — and confirm with your vet that it's appropriate for your dog's specific liver condition and stage.
Place fish fillet in unsalted water. Bring to a gentle simmer and poach 8–10 minutes until completely cooked through. No salt, no oil. Remove, cool slightly, and flake into small pieces. White fish is the lowest-copper animal protein available — this is the main reason it's chosen over chicken, beef or organ meat.
Cook white rice until soft and slightly sticky. The higher carbohydrate proportion in this recipe (compared to standard bowls) is intentional — glucose energy from rice spares the liver from having to convert protein and fat, reducing its workload.
Steam broccoli for exactly 4–5 minutes — just enough to cook but not destroy sulforaphane. Boil carrot and sweet potato until completely soft. For dogs with reduced appetite (common in liver disease), fully soft textures are more appealing and easier to eat.
💡 If appetite is very poor, add a small splash of unsalted low-sodium broth to improve palatabilityAdd fish, rice, vegetables and blueberries to the bowl. Let cool fully to room temperature before adding any supplements.
Stir in salmon oil and eggshell calcium only after the bowl has cooled. Both must go in cold to preserve their function.
Certain breeds have a documented hereditary predisposition to liver conditions, particularly copper storage disease (copper toxicosis). If you own one of these breeds, annual liver enzyme screening (ALT, ALP, bile acids) from middle age is recommended — liver disease is often silent until 75% or more of liver function is lost.
Beef liver, chicken liver, kidney and heart are eliminated entirely from this recipe — they are among the highest-copper foods in any dog diet. Shellfish (oysters, mussels, clams) are also excluded — oysters contain one of the highest concentrations of copper per gram of any food. No dairy, no processed treats with additives. For dogs with hepatic encephalopathy, protein must be restricted further, and your vet may prescribe a commercial hepatic diet rather than a homemade recipe at that stage.
