Dog Liver Failure Signs - A Comprehensive Guide

Liver failure is a serious health condition that can affect our canine companions. It occurs when the liver is no longer able to function properly and remove toxins from the body. This buildup of toxins can cause severe symptoms and can be life-threatening if not treated promptly. Unfortunately liver disease is reasonably common in dogs, especially in older animals. There are a number of potential causes for liver failure in dogs, including infection, cancer, toxicity, genetic conditions, and more. Some breeds may also be predisposed to certain types of liver disease.


That's why it's critical for dog owners to recognize the signs of liver failure in dogs as early as possible. When caught early, liver failure can often be treated successfully. But delaying veterinary care could allow permanent liver damage to occur. Getting immediate treatment greatly improves your dog's prognosis and increases their chances of making a full recovery.


In this comprehensive guide, we will cover everything you need to know about liver failure in dogs. We'll discuss the most common signs and symptoms, how it's diagnosed, treatment options, and steps you can take at home to help your dog. We'll also provide tips to help prevent liver problems. Arm yourself with information so you can best monitor your dog's health and get them treatment at the first sign of trouble.



Signs and Symptoms


There are a number of signs and symptoms that could potentially indicate your dog is suffering from liver failure. Being aware of these warning signs is crucial, as early veterinary treatment greatly improves prognosis. Here are some of the most common signs of liver problems in dogs:


  1. Loss of appetite - One of the first signs of liver issues is a refusal to eat. This occurs because toxins building up in the bloodstream cause nausea.
  2. Vomiting and diarrhea - Along with a loss of appetite, many dogs will also begin vomiting or have diarrhea. There may be blood or a strange color in the vomit or stool.
  3. Increased thirst and urination - The kidneys have to work harder to filter the toxins out, so dogs may start drinking and urinating more.
  4. Weight loss - Despite eating less, dogs tend to lose weight rapidly due to deficiencies in nutrient absorption.
  5. Abdominal swelling - Fluid accumulation in the abdomen, called ascites, leads to an enlarged belly.
  6. Jaundice - A yellowing of the gums, eyes, or skin results from a buildup of bilirubin in the blood.
  7. Changes in stool - Black and tarry stool often occurs due to bleeding into the stomach and intestines.
  8. Increased sleeping - Due to feeling unwell, dogs suffering from liver failure tend to sleep and rest more.
  9. Confusion or disorientation - Toxins in the blood affect brain function, so dogs may act confused or seem to get lost in the house.
  10. Bleeding disorders - Nosebleeds and easy bruising are common as clotting factors are impacted.
  11. Fever - An elevated body temperature can point to an underlying infection damaging the liver.
  12. Painful abdomen - Dogs may whimper or cry when their belly is touched due to liver pain and inflammation.




If your dog is exhibiting any of the symptoms of liver disease, it's imperative to schedule an appointment with your veterinarian right away. Timely diagnosis and treatment is essential.

To determine if your dog has liver failure, the vet will start with a full physical examination, checking for enlarged organs or painful reactions. They will also ask you about any symptoms you have observed.


Some common diagnostic tests your vet may perform include:

  • Blood tests - Complete blood counts and blood chemistry panels can detect elevated liver enzymes and bilirubin levels.
  • Urinalysis - An analysis of your dog's urine can provide further evidence of liver problems.
  • Imaging - X-rays, ultrasound, CT scans, or MRI can identify liver abnormalities, tumors, and enlargement.
  • Liver biopsy - In some cases, removing a small sample of liver tissue for examination under a microscope may be recommended. This is the most definitive way to diagnose liver disease.


Your vet will evaluate all the test results to determine if your dog has liver failure and if so, the underlying cause. Once the problem is identified, appropriate treatment can begin right away. It's crucial not to delay medical care, as the condition can rapidly deteriorate. Inform your vet of all your dog's symptoms, and be sure to follow all their recommendations for tests and prompt treatment.





Treatment of liver failure in dogs will depend on the underlying cause and how far the disease has progressed. In many cases, hospitalization and intensive care is needed, especially initially. Treatments your vet may utilize include:


  • IV fluids - Administering intravenous fluids helps maintain hydration and prevents dangerous drops in blood pressure.
  • Medications - Drugs to control nausea, vomiting, and diarrhea are often prescribed. Antibiotics may be used if infection is present.
  • Diet changes - Eating small meals of bland, low-fat, high-protein food supports liver function.
  • Vitamin supplements - B vitamins and Vitamin K can be deficient and need replacement.
  • Treatment of coagulation disorders - Transfusions of plasma or clotting factors may be required for bleeding problems.
  • Surgery - If a liver shunt is present, surgery can be done to repair it. Tumors may also need surgical removal.
  • Medical procedures - Therapies like plasmapheresis help clear toxins from the blood.
  • Liver transplant - For end-stage liver failure, a transplant could be an option, especially in younger dogs.


During treatment, your vet will continue to monitor bloodwork closely. As the liver starts to heal, enzyme levels should gradually return to normal. But recovery can take awhile, depending on the amount of liver damage. Your dog may need extensive care for days, weeks, or sometimes months in severe cases. Closely follow all your vet's home care instructions for medications, diet, and follow up. Report any concerns right away.



Prognosis and Outcomes


The prognosis for dogs with liver failure can vary considerably depending on the underlying cause and how quickly treatment was started.

For cases caused by a treatable illness like infection or toxicity, the prognosis is often good if treated promptly. With aggressive therapy, many dogs can make a full recovery.

If liver failure is due to an irreversible disease like cancer or cirrhosis, it may only be possible to manage the condition long-term instead of curing it. But dogs can still live happy lives for years with proper care.

For cases caught very late or those who are not responding well to treatment, liver failure can be fatal. The toxins and fluid buildup eventually become too much for the body to handle.

Dogs who recover from an episode of liver failure need continued monitoring. Some may experience chronic liver problems or even suffer from liver failure again in the future. But checkups and blood tests allow vets to stay on top of any recurrent issues.


Talk with your vet in depth about your individual dog's condition, treatment options, and prognosis. Be sure to follow all recommendations for medications, diet, and recheck exams after treatment. While liver failure is serious, keep a positive outlook, as many dogs recover and thrive if given prompt and proper veterinary care.



At Home Care and Prevention


Caring for your dog after a liver failure diagnosis requires close adherence to your veterinarian's instructions. Be sure to:


  • Give all medications exactly as prescribed. Don't miss doses.
  • Feed the recommended therapeutic diet. Low fat, highly digestible proteins support the liver's recovery.
  • Avoid any chemicals or toxins - keep medications, cleaners, plants out of reach.
  • Monitor for any return of symptoms and contact the vet immediately if they occur.
  • Attend all follow up vet visits for bloodwork to ensure your dog's liver values stay normal.
  • Feed smaller, more frequent meals rather than one large daily portion.



There are also steps you can take to help prevent liver disease in your dog:


  1. Have your vet run annual bloodwork to screen liver enzymes, even when your dog seems healthy.
  2. Vaccinate your dog to protect against infectious diseases that could damage the liver like leptospirosis.
  3. Avoid feeding high fat foods which can contribute to inflammation and liver stress.
  4. Know the signs of liver toxicity and seek treatment promptly if ingestion occurs.
  5. Don't let your dog roam loose outside where they could consume toxins or poisonous plants.
  6. Have any cancers diagnosed early when treatment is most effective.
  7. Make sure your dog maintains a healthy weight to reduce liver strain.


Stay vigilant for any signs of liver trouble and be prepared to get your dog prompt veterinary care. This gives you the best ability to catch problems early and improve the odds of a full recovery.




Liver failure is a very serious condition that requires emergency veterinary treatment. As a dog owner, being able to recognize the signs of liver disease could truly save your best friend's life. Look for symptoms like vomiting, diarrhea, jaundice, weight loss, bleeding issues, fluid buildup, and behavioral changes. If you observe any of these, get your dog to the vet without delay for diagnostic testing.


With aggressive therapy like hospitalization, medications, IV fluids, and dietary changes, many dogs can recover fully if liver failure is caught early. Work closely with your veterinarian to get your dog promptly diagnosed and treated. Follow all at home care instructions carefully, including giving medications, feeding a therapeutic diet, and monitoring your dog's symptoms.


While a liver failure diagnosis is scary, try to stay positive. The treatments available today can be very effective if started quickly. Focus your efforts on getting your dog the best veterinary care possible. With your diligent attention and nursing, your pup can hopefully make a full turnaround. Stay hopeful and know that many dogs go on to live happy, normal lives after successful treatment.
