Treating and preventing liver disease naturally

by Dr. Peter Dobias, DVM
Why a liver cleanse for your dog may extend their life expectancy

Allow me to disagree with some of my colleagues who claim raw food diet feeding is a fad. In my 25 years of clinical practice, I have confirmed that feeding a raw diet can treat many ailments, including liver disease.

If you are tired of hearing about processed kibble and canned food recalls, you are not alone. Dog lovers, like you, are starting to realize that feeding raw food is the most effective way to keep your dog healthy. In my experience, quality raw pet food can extend your dog's and cat’s life by two to five years on average. One of the reasons is it helps maintain the liver's health and optimal function.

The liver has several main functions:

  • It is a cleansing organ that rids the body of toxins through chemical transformation or excretion in bile

  • Bile also aids in digestion of fats 

  • The liver produces glycogen, a starch analogue, which serves as energy storage 

  • The liver is responsible for protein production

Assessing liver health

The level of hepatic (liver) activity can be determined by evaluating liver enzymes through a blood test.

ALT (Alanine aminotransferase) is the most important enzyme in the assessment. It is also sometimes called SGPT (serum glutamic-pyruvic transaminase). ALT is almost exclusively found within hepatocytes (liver cells). An increase in ALT is highly specific to liver cell injury in dogs and cats.

AST (Aspartate Aminotransferase) activity primarily reflects liver and muscle disease, with less specificity to the liver than ALT. It can be elevated by liver infections, chronic non-infectious inflammation or degeneration of the liver.

GGT (Gamma Glutamyl Transferase) is usually elevated in cases of cholestasis (bile stagnation) in the liver itself or by obstructed bile ducts.

ALP (Alkaline Phosphatase) may also  be elevated in the case of liver disease, drug administration or any inflammatory processes in the body. This enzyme doesn’t have a great practical use in liver function evaluation.

Elevated ALT 

Some dogs, even those fed a raw diet, can have elevated ALT. If it is less than two times the normal value it may be because of liver disease, especially in dogs fed processed foods. However, it may also be found in dogs fed raw food that have higher healthy enzymatic activity.  

(I do not mention specific numbers here as the reference range varies from lab to lab and the units from country to country.)

Values higher than two times the normal range suggest liver disease and medical attention is likely needed.

Keep your dog’s liver in top notch shape

A liver cleanse is one of the most important elements for creating a healthy and long life for your dog. To be sure that your dog’s liver is functioning optimally, I recommend the following liver cleansing protocol.

If you are not ready to feed raw, the first step is to feed the highest quality, non-medicated, unprocessed, raw or cooked food. Feeding most processed food or raw food made of medicated chicken, turkey and poor-quality, rendered meats can cause serious problems, nutritional deficiencies and can also overburden the liver.

Avoid processed prescription liver diets

Processed pet food giants have long seen the opportunity of selling exclusive veterinary diets for treatment of liver disease. All you need to do is to check the ingredients and you will see what is really going on:

"Brewers Rice, Pork Fat (preserved with mixed tocopherols and citric acid), Dried Egg Product, Soybean Meal, Powdered Cellulose, Flaxseed, Pork Protein Isolate, Chicken Liver Flavor, Dicalcium Phosphate, Lactic Acid, Soybean Oil, Potassium Chloride, Dried Beet Pulp, Calcium Carbonate, Glycerol Monostearate....."

Really? Pork fat for liver disease?

In my opinion, low protein food is harmful considering the ingredients. Feeding such a diet is like trying to purify drinking water by pouring sewage in it!

Practical steps for a time-tested liver cleanse

The liver is an important organ in almost every aspect of your dog’s organ function and good health. I take my dog Skai through a good liver cleanse twice a year. You will see a regular cleansing has a very positive effect on your dogs health, namely in their overall energy level, mobility, digestion, endurance and stamina, skin and coat health, immune system function and cancer prevention.

  1. Even if your dog doesn’t have any liver enzyme elevation, a liver detox every six to 12 months is considered highly beneficial in dogs. Canines in general have a tendency for liver imbalances.

  2. Feed lower fat meats. Avoid kibble or canned food or raw, rich and greasy meats such as duck, fatty lamb, bison, buffalo and beef or meat rendered from meat packing plants.

  3. Avoid feeding large marrow bones, which have extremely high fat content.

  4. Beware of cheap treats even if they are natural. If it is too cheap it is likely because the ingredients are cheap too.

  5. Avoid any food made in China because of that country's history of tainted foods and heavy use of additives and chemical preservatives.

  6. Start a one to two-month course of Liver Support and Cleanse (Livton) - a liver cleansing herbal formula that has been very effective for myself and Skai.

  7. Administer and continue giving GreenMin on an ongoing basis to detox  and provide essential minerals and nutrients.

  8. After the liver cleanse is completed start essential supplements to provide the body what it needs to heal and thrive.

  9. If your dog has elevated liver enzymes to any degree, measure ALT values at least every three to six months depending on the severity of the problem and seek the help of an experienced animal care provider.

  10. If the ALT values do not start dropping within three months start Zyflamend. I have seen this product reduce ALT by half in some very severe hepatitis cases. Continue this product for two months after the liver enzymes are back to normal. 

Should supplements be given during a liver cleanse?
  • Generally, it is ok to continue the essential supplements such as GreenMin, SoulFood, GutSense and Omega in the course of the liver cleanse

  • If your dog has never been on any supplements I suggest starting with Greenmin, Livton and Gutsense first and start SoulFood and other supplements one month later. 
Note about liver cleansing foods

There are some foods known to have a highly positive effect on the liver.

Bile flow and liver flow can be promoted by adding leafy greens and also watercress, basil and turmeric.
You can harmonize the liver by adding apple cider vinegar (1/4 tsp to 1 tsp) into food to promote cleansing.
Romaine lettuce, dandelion leaves and chamomile flowers all have a positive effect on the liver.
