Liver Disease In Dogs And Its Treatments

Liver disease in dogs is the fifth leading cause of non-accidental death among dogs.  It is a very serious condition.  Since the liver is the largest and most important organ in the body. The body becomes toxic and starts to deteriorate if it’s not working properly.  The liver is a complex organ.  It filters your dog’s entire blood supply many times each day.  It processes everything that the body is exposed to, both internally and externally.  It performs many vital functions, including detoxifying the blood of drugs and poisons; removing ammonia and other wastes from the blood; manufacturing blood-clotting factors; and synthesizing enzymes, proteins and metabolites.

Liver Disease In Dogs

The liver has a phenomenal ability to regain function and is believed to be capable of complete regeneration.  When liver disease is identified early on, there is a chance of complete recovery.  However, early diagnosis and treatment of liver disease in dogs is extremely difficult.  The liver can perform its function without discernible changes in blood analyses with up to 75 percent of it affected by disease.  This means the disease is usually well advanced, and possibly untreatable, before any symptoms are noted.

Liver disease is a catch-all term that applies to any medical disorder that affects the liver.  There are many different specific and non-specific diseases of the liver.  Your Vet will need to do further diagnosis to determine the cause and best treatment.  Because of the complexity of liver disease in dogs.

Liver Disease in Dogs Causes 

  • Prolonged use of some drugs such as NSAID’s (Non-Steroidal Anti-Inflammatory Drug), cortisone, anti-convulsants, steroids, some antibiotics, anesthetics, parasite control drugs, chemotherapy drugs and acetaminophen.
  • Exposure to high levels of toxic chemicals like insecticides, lead, phosphorus, selenium, arsenic and iron.
  • Other diseases, viruses and infections like hepatitis, heartworms, and infections elsewhere in the body; most commonly dental disease, chronic skin and ear infections.
  • Certain breeds of dogs are prone to genetically inherited liver disease (female Doberman Pinschers, American and English Cocker Spaniels, Bedlington Terriers, West Highland White Terriers).
  • In-breeding.

Common Symptoms of Liver Disease

  • Diarrhea with or without blood.
  • Eating unusual things.

Cirrhosis of the Liver

Liver Disease In Dogs

Cirrhosis is the final stage of liver disease in dogs. It is when the liver cells die off and turn into scar tissue.  This condition is irreversible.  The only treatment option is dietary care.  The liver can still function with up to 70-80 percent of the liver affected. Cellular regeneration is not possible once the tissue is scarred.  The only hope is to keep the part of the liver that remains as healthy as possible.

Liver Disease Diagnosing in Dogs

  • Examination to identify the specific signs of liver disease.
  • Consultation with Vet (most important) to get a full history (when, where, why, how, etc.) and more to determine when the liver disease started and what could be causing it, so that whatever’s causing it can be stopped.
  • Blood Test  to check for anemia, other organic abnormalities, health of the bile system, infections, electrolyte imbalances, digestive enzymes, blood parasites, blood proteins, blood sugar (glucose), liver enzymes and ammonia.
  • Ultrasound  to visually inspect for scar tissue, cancer, abscesses, abnormal blood supply, to determine what percentage of the liver is affected and determine the size and density of the liver, gall bladder and bile system.
  • Biopsy to give a microscopic perspective to ascertain diagnosis, the actual conditions of the liver cells and prognosis to better determine appropriate treatment.

 

Liver Disease Treatments For Dogs
