Diet plays an important role in pets’ recovery from (or management of) any liver disease. The best liver disease diet for your pet depends on the condition your pet is suffering from and its severity. For example, if your dog suffers from copper storage disease, then he needs to be put on a diet that is low in copper.

The best cat liver disease diet is not necessarily the best dog liver disease diet. However, there are some common dietary adjustments and nutritional supplements that are generally recommended for pets recovering, or suffering, from liver diseases. 

It is common that cats and dogs with liver disease have reduced appetite. They may even refuse to eat at all. In those cases, force feeding with a syringe or feeding tube may be necessary to make sure the animal gets the right nutrition and calories.

When the initial condition has been brought under control it is important to start feeding again but some dietary adjustment is normally recommended to help the liver to recover. Even when the liver is damaged beyond repair, the diet still plays an important role in the management / supportive care of the disease.

What is the ideal protein intake for your pet depends on what liver disease your pet is suffering from and what stage it is.

It is important to bear in mind that not all protein is equal. High quality protein reduces the workload on the liver and studies have shown that non-meat protein sources (dairy, soy, and eggs) work better than meat sources for pets with liver diseases.

Protein restriction is sometimes recommended.

However, recent studies indicate that protein requirements are greater for pets that are recovering from hepatic disease. Dietary protein should therefore only be reduced if there is a sign of protein intolerance.

Carbohydrates

Pets with hepatic disease need carefully regulated portions of high quality and highly digestible carbohydrates. White rice, potatoes, and vegetables are good source of simple and complex carbohydrates for pets with liver diseases.

Simple carbohydrates are easily digested and absorbed. While vegetables provide fiber (non-digestible complex carbohydrates) but fibre reduces the availability and absorption of toxins like endotoxin, bacterial toxins, and some bile acids.

Fats

High quality fats are important part of our pet's diet. Fat is good source of calories and essential fatty acids (that must be obtained through the diet). Fats also enhance the food palatability. 

Numbers of studies have shown that cats and dogs with hepatic disease do well on diets containing 20 – 25% fat (Dog Cat Home Prepared Diet).

Sodium (Salt)

The salt content should always be carefully monitored in feline & canine liver disease diet. Low sodium diet helps with ascites (extra fluid in the abdomen) but ascites is common in many hepatic diseases.
