Food for dogs with a liver shunt
A liver shunt needs a vet-prescribed diet, usually a moderate, high-quality protein food that reduces the toxin load on a liver that isn't filtering blood normally the way it should. There isn't an over-the-counter equivalent to a proper prescription diet, and this isn't a condition to manage with a shop-bought food alone.
What a liver shunt actually is
A liver shunt, or portosystemic shunt, is an abnormal blood vessel that allows blood to bypass the liver rather than passing through it to be filtered as normal. That matters because the liver's job includes clearing toxins produced during normal digestion, particularly from protein breakdown, and a shunt means some of that isn't happening properly.
This is why diet becomes such a central part of managing the condition. Reducing the toxin load reaching the rest of the body — largely by managing protein quality and quantity carefully — takes some of the pressure off a liver that's already working at a disadvantage.
Why this needs a vet-prescribed diet, not a shop choice
Genuine liver-support diets are formulated with a very specific balance of protein source, quantity and other nutrients, and getting that balance wrong in either direction can do real harm — too much protein increases the toxin load the condition is trying to reduce, while too little causes its own nutritional problems. This isn't a diet you can safely approximate by picking a food off a shelf based on marketing language.
These diets are typically only available on veterinary prescription, and that's true across the pet food market generally, not specific to any one shop. If you're looking for a liver-support food, that conversation starts with your vet, who can prescribe the right formulation and dose it to your dog's specific situation, often alongside monitoring and sometimes surgery depending on the shunt itself.
What to look for if you're reading a label
A liver-support diet typically favours protein sources that are considered easier on the liver, moderate rather than very high overall protein content, and controlled copper levels, since excess dietary copper can add further strain in some liver conditions. None of this is something to self-select without veterinary guidance, but understanding the reasoning helps you follow your vet's recommendation with more confidence.
Never adjust a diagnosed dog's diet based on general information like this alone, and never reduce protein sharply on your own — a liver shunt diet is a precise, individualised prescription, not a category of food you can safely guess your way into.
What we can genuinely offer alongside a vet's plan
A slow feeder can help a dog on a carefully portioned diet make a smaller meal last longer and feel more satisfying, which is a genuinely useful, low-risk addition alongside whatever your vet has prescribed. It doesn't affect the diet itself, just the pace and experience of eating it.
Beyond that, this is a condition where the right next step is your vet's prescription and monitoring, not a product we can responsibly recommend as a treatment. If your dog has been diagnosed with a liver shunt, that conversation should already be underway with the vet managing the case.

Common questions
- Can I buy a liver-support dog food without a prescription?
- Genuine liver-support diets are formulated to a precise balance and are typically only available on veterinary prescription, which is standard across the pet food market rather than specific to any one retailer. Speak to your vet if your dog needs one.
- Why does protein matter so much for a dog with a liver shunt?
- The liver normally clears toxins produced when protein is digested, and a shunt means blood bypasses that filtering process. Managing protein quality and quantity carefully reduces the toxin load reaching the rest of the body, which is why it's central to how the condition is managed.
- Can diet alone manage a liver shunt?
- Sometimes diet is part of ongoing management, and in other cases surgery is needed depending on the specific shunt. This varies by individual dog, which is exactly why it needs your vet's assessment rather than a general answer.
- What are the signs my dog might have a liver shunt?
- Signs can include poor growth, lethargy, disorientation after eating, vomiting or seizures in more severe cases, though these can also point to other conditions entirely. Any of these signs warrant a vet visit for proper diagnosis rather than guessing at the cause.
