The Liver’s Functions

The liver is one of the most important organs in the dog’s body. The liver is the largest organ and it performs around almost 1,500 functions.

The liver plays an important role in the metabolism by performing a multitude of functions, including detoxification, mineral storage, glycogen storage and blood protein production.

The liver also produces bile, which is important during digestion of food. Several diseases cause reduced function of the liver and/or  its efficiency.  However, the liver is the only organ in a dog which can be recovered in full with the proper treatment, even when the damage is greater than 70 percent!

Liver Problems in Dogs 

Liver disease can be congenital or acquired. Congenital simply means medical conditions that are present at birth or before birth, while acquired means conditions that develop over a course of the dog’s life. There are 3 types of liver changes that can cause pathological behavior in its function:

  •  Changes in cellular structure (inflammatory reaction, tumors)
  •  Changes in biliary system (inflammatory or obstructive
  •  Changes in vascular system

The most usual causes for these changes may be liver masses, tumors, non-tumor masses, hepatic cyst, congenital vessel abnormalities such as congenital portosystemic shunt or acquired shunt due to hypertension or cirrhosis,  endocrine diseases, diabetes mellitus, hyperadrenocorticism ( also known as Cushing’s disease), hyperthyroidism diseases of other organs that jeopardize the function of the liver (heart, kidneys), infective diseases (bacterial, viral and fungal).

Various toxic substances such as pesticides, rodent poisons, chemicals such as antifreeze, alcohol, algae, mushrooms, etc can lead to liver problems and so can excessive intake of certain drugs.

Hepatitis is a viral disease of which may infect dogs of all ages and causes  serious damage to the liver, blood vessels, and kidneys. Other conditions that affect the liver include leptospirosis, salmonellosis, coccidioidomycosis and histoplasmosis, toxoplasmosis, copper storage disease. A history of abdominal trauma may be a culprit too.

Did you know?  Certain breeds of dogs are genetically predisposed liver problems such as West Highland white terriers, cocker spaniels, Doberman pinschers.

Symptoms of Liver Problems in Dogs 

The first symptoms of liver disease in dogs are generic and common to many diseases, such as high fever, blood in stool, diarrhea, and loss of appetite and vomiting.

There are only a few symptoms that could be called specific for liver disease, but still, they may be a sign of other diseases as well. Some of the symptoms suggestive of liver disease are jaundice (yellowing of mucous membranes), increased thirst, increased urination, and off-white color of feces, loss of appetite, weight loss, and enlarged abdomen due to an accumulation of fluid (ascites) or an increase in the liver itself, nervous symptoms.

Infectious canine hepatitis can cause cloudy corneas in one or both eyes and this is called the Blue Eye, but this symptom is not unique to this disease.

Treatment for Liver Problems in Dogs 

In most cases of liver disease, there isn’t any specific treatment, but it boils down to support and symptomatic treatment as well as special diet that which is crucial.

The method of treatment depends on the form of liver disease. In milder forms slightly changed diet with supplementation of vitamins gives very good results. In chronic diseases, the treatment is prolonged with the use of appropriate drugs and special veterinary diets.

The type of therapy that will be given depends on the type of disease and the degree of liver damage.

  • Corticosteroids such as prednisone are used as anti-inflammatory medicine, and to decrease scarring of the tissue. They also stimulate appetite, but due to the fact that each drug is metabolized in the liver, it should be used wisely.
  • Antibiotics are used in cases of bacterial liver infection, or when the patient is at risk of a secondary infection due to overall status. They are chosen based on the lab results, knowing the bacterial flora of the liver, but broad spectrum antibiotics are always a good choice.
  • Antioxidants such as vitamin E, N-Acetylcysteine, S-Adenosylmethionine, Whey Protein and Silibinin (Milk Thistle), are most important because, during liver stress or any disease, levels of glutathione in the liver are abnormally decreased. Glutathione or GSH is called the Mother of antioxidants, and its role is to prevent intracellular damage.
  • Penicillamine and Zinc are used in copper storage disease to reduce the amount of copper. Zinc increases synthesis of metallothionine which binds copper.
  • Antiulcer drugs
  • Antiemetic drugs to cure vomiting and nausea.
  • Diuretics for treating ascites.
  • Electrolytes for preventing dehydration due to ascites, vomiting, diarrhea.

Diets for Dog Liver Disease 

Regardless of the type of liver disease, or the extent of liver damage, the diet must be modified, sometimes just in the means to maintain proper nutrition and caloric intake, and sometimes specific diets may be recommended. Most basic facts for dog`s diet during liver problems are mentioned below;

Proteins

Due to the fact that less protein is being processed in the liver, your dog`s diet must contain high-quality proteins but their levels must be moderate. High-quality proteins have a high biological value, they are good calorie sources, and they are easily digested. Good protein sources (that are also low in copper, which is important) are turkey, chicken, white fish, beef.

” As a general recommendation the dietary protein should represent 17 to 22% of digestible Kcal.”~ David Twedt, DVM, DACVIM

Fats

Dogs with liver disease can tolerate larger quantities of fat in their diet (30 – 50% of calories), and non-protein calories help reduce the need of gluconeogenesis, which happens in the liver, and further burdens the organ.

Fibers

Fibers are important because some types help remove ammonia and reduce bile acids.

Carbohydrates

Carbs aids digestion, so oatmeal or rice is a good start.

Vitamins

Vitamin K helps bleeding disorders and clothing problems since the liver is the biggest producer and depot of this vitamin. In sick liver, this depot cannot be used, so it must be added as supplement. Vitamin E and Vitamin C are powerful antioxidants.Vitamin B complex.

Dog diets should be low in potassium and copper.

Dogs with the aforementioned problems often have little to no appetite, and sometimes it is necessary to force feed them with syringe or feeding tube.

Final Notes 

Most of the liver problems are acute, and if treated on time with proper care, results are more than satisfactory. On the other hand, some types of liver problems are not curable or far gone, but with supportive care and medication, your pet friend may live a comfortable life.
