Liver Supplements for Dogs & Cats

Written by: Dr. Jean Hofve, Holistic Veterinarian, DVM

Do Dogs & Cats Need Liver Support?

The liver is one of the most important organs in the body. It is a crucial part of the digestive system, as well as playing a role in the immune system. Most blood from the intestinal tract is routed through the liver for detoxification. The liver can operate effectively with only 20% of its cells working, so it has a large reserve capacity. Without the liver, the body is doomed within days. But the good news is that, with proper support, the liver can completely regenerate itself after injury or disease. These traits make the liver truly remarkable; and mean that even serious liver disease is survivable and has a much better prognosis than similar damage to other organs.

"The liver is one of the most important organs in the body."

The liver is also one of the few organs with key differences between dogs and cats. The dog’s liver is very similar to that of humans and other mammals. However, a cat’s liver contains fewer metabolic enzymes and has a diminished ability to handle toxins. The development of liver disease is also due to different causes between dogs and cats. In dogs, liver failure is commonly due to congenital problems, traumatic injury, infections, or other disease. Cats, on the other hand, can develop liver disease not only from infection or trauma, but also from seemingly minor stresses, such as not eating enough for whatever reason.

Keeping the Liver Healthy in Dogs & Cats

Preventing liver disease is a whole lot easier than curing it. A high-quality diet, including at least some wet food for both dogs and cats, is the first and most basic step. Additionally, there are herbal and nutritional supplements that can support and strengthen the liver so that it can handle damage and disease more efficiently. Supportive supplements with specific benefits for the liver include:

Does Your Dog or Cat Have Liver Issues?

In dogs with liver disease, a precise diagnosis is important. This usually involves blood tests, and possibly also ultrasound or even biopsy of the liver. Different causes need different treatment. For example, in a puppy with a liver shunt (an abnormal blood vessel that bypasses the important detoxification processes of the liver), a high protein diet—which is normally fine for the liver—could be deadly. Cats have a less diverse potential problem list, mostly involving either inflammation or hepatic lipidosis (fatty liver disease). Signs are similar, and treatment in cats nearly always comes down to: “feed the liver,” although specific treatment with antibiotics or anti-inflammatory drugs may be needed, depending on the cause of the problem. Unfortunately, feeding an animal with liver disease both crucial and difficult, since these pets tend to not want to eat at all. Force-feeding or even surgical placement of a feeding tube may be necessary components of treatment. Just mix the supplements with a little blended canned food, and force-feed the mixture by syringe or via tube. Here are a few tips to make this process easier:

  • Mix up the whole day’s worth of food in the morning, with all the supplements in it.
  • Set aside a portion for the first feeding, and put the remainder in the refrigerator.
  • For subsequent feedings, take out the appropriate portion, mix a little hot water in to warm and soften it, and you’re ready to go.

The herb milk thistle is an important healer for the liver in times of stress or disease. It protects the liver from toxins and helps it regenerate. The active ingredient of milk thistle, “silymarin,” reaches high levels in the bile and liver tissue. It can be used in the treatment of hepatic lipidosis, chronic hepatitis (generalized liver inflammation), cholangitis (inflammation of the bile ducts), and pericholangitis (inflammation of the tissue around the bile ducts). It may be useful in preventing or treating some liver problems, as well as gallstones, by thinning the bile. It is very safe. You can give up to 250 mg of milk thistle daily for every 10 pounds of your pet’s body weight. It is most effective when given in smaller portions throughout the day than in one big dose. Two of our favorite milk thistle products are:

  • Super Milk Thistle X
  • Only Natural Pet Liv-Herb Herbal Formula

Omega-3 fatty acids can be given at higher doses for a sick animal. Give 2 or 3 times the normally recommended amount; up to 3,000 mg per day for a large dog.

Carnitine, an amino acid, is extremely important for cats with hepatic lipidosis, but is helpful for all dogs and cats, especially those who eat a lot of high-carbohydrate dry food. Give 250-500 mg/day for a cat. Carnitine is also important for heart muscle function in both dogs and cats. Our highest potency products are:

  • Vetri-Science Cardio-Strength
  • Vitaline L-Carnitine

"A pet with liver disease needs professional care from your veterinarian, but you can greatly help the healing process with the right supplements, and of course plenty of TLC!"
