What Causes Liver Failure in Dogs [10 Hints]

What causes liver failure in dogs? Let’s find out together…

As pet parents, we try our best to keep our furry friends healthy and happy, but what happens when our beloved pups experience liver failure?

This scary condition can be caused by a variety of factors, from toxins to genetic predisposition.

In this blog post, we’ll explore the different causes of liver failure in dogs, so you can keep your pup’s liver healthy and functioning properly.

What is liver failure in dogs?

Liver failure in dogs is a medical condition where the liver is unable to function properly.

The liver plays a crucial role in processing and removing toxins from the body, as well as producing important proteins that are necessary for the body’s normal processes.

When the liver is unable to perform these functions, it can lead to serious health problems, including jaundice, seizures, and even coma or death.

There are many possible causes of liver failure in dogs, including viral infections, cancer, autoimmune diseases, and poisoning from medications or toxic substances.

Symptoms can include vomiting, diarrhea, lethargy, and loss of appetite, among others.

Prompt veterinary care is necessary if you suspect your dog may be experiencing liver failure.

What Causes Liver Failure in Dogs

There are several potential causes of liver failure in dogs, including viral or bacterial infections, exposure to toxins, congenital defects, and certain medications.

Other factors, such as heartworm disease and high blood pressure, can also contribute to liver damage.

In some cases, the exact cause of liver failure may be difficult to determine.

If you suspect your dog may be experiencing liver problems, it’s important to seek veterinary care as soon as possible.

Let’s break it down further…

Potential Causes of Liver Failure in Dogs

The following are some of the most common causes of liver failure in dogs:

1. Parasites

Parasites in dogs can be a common cause of liver failure in dogs. These parasites, such as heartworms, roundworms, and fleas, can damage the liver and other organs as they travel through the bloodstream.

In addition, parasites such as liver flukes and tapeworms can infect the liver directly and cause damage over time.

Treatment for parasite-induced liver failure in dogs typically involves antiparasitic medications to eliminate the parasites and reduce their impact on the liver and other organs.

Supportive care, such as intravenous fluids and nutritional support, may also be necessary. In severe cases, surgery may be needed to remove any blockages or damage caused by the parasites.

Preventing parasitic infections in dogs is essential for avoiding liver failure and other serious health problems. This can be accomplished through regular deworming, heartworm prevention, and flea and tick control.

Additionally, good hygiene and sanitation practices can help reduce exposure to parasites and other infectious agents. Regular check-ups with a veterinarian can help identify and treat parasitic infections early on before they cause serious health problems.

2. Toxic Ingestion

Toxic ingestion is a common cause of liver failure in dogs and occurs when a dog ingests a toxic substance that damages the liver.

Common toxins that can cause liver damage in dogs include rodenticides, certain medications, poisonous plants, and harmful algal blooms.

Treatment for toxic ingestion in dogs involves removing the toxic substance from the dog’s system and addressing any related symptoms.

This may involve inducing vomiting or administering activated charcoal to absorb the toxin. In severe cases, hospitalization may be necessary, including fluid therapy and supportive care.

Prevention of toxic ingestion in dogs involves keeping all potentially harmful substances out of reach of the dog and avoiding exposure to known toxins, such as cyanobacterial blooms.

If you suspect that your dog has ingested a toxic substance, it is essential to seek veterinary care immediately to prevent liver failure and other serious health complications.

3. Infectious Diseases

Infectious diseases such as Canine Parvovirus, Leptospirosis, Infectious Canine Hepatitis, and others can lead to liver failure in dogs. These diseases typically attack the liver and cause damage, leading to decreased liver function and potential failure.

Treatment for liver failure caused by infectious diseases in dogs typically involves addressing the underlying disease first.

This may involve hospitalization, fluid therapy, and medications to manage symptoms and fight the infection. In some cases, surgery may be necessary to remove damaged tissue or address complications such as bleeding.

Prevention of these infectious diseases in dogs can often be achieved through vaccinations and proper hygiene. Ensuring that your dog is up to date on their vaccinations and avoiding contact with infected animals can help reduce the risk of contracting these diseases.

Additionally, practicing good hygiene such as washing your hands regularly and cleaning your dog’s food and water dishes can help prevent the spread of disease.

4. Portosystemic Shunts

Portosystemic shunts occur when blood from the intestine bypasses the liver and flows directly into systemic circulation. While most shunts in dogs are congenital, acquired shunts can also occur as a result of scarring from liver disease.

The most common signs of liver failure in dogs with a portosystemic shunt are vomiting, diarrhea, and weight loss.

Treatment for portosystemic shunts in dogs involves surgery to close the shunt or create a new pathway for the blood to flow through the liver.

Medical management can also be used to control the symptoms associated with the disease, including a low-protein diet, medication to control ammonia levels, and antibiotics to prevent infections that can occur due to bacterial translocation from the intestine.

Prevention of liver failure due to portosystemic shunts in dogs involves proper breeding practices, as shunts are often inherited.

It is recommended that dogs with a history of the disease not be bred and that puppies from litters with affected individuals be evaluated for the presence of a shunt.

Early detection and intervention can improve the outcome for dogs with portosystemic shunts and reduce the risk of liver failure.

5. Tumors

Liver tumors in dogs refer to the abnormal growth of cells within the liver, which may lead to liver failure.

Some of the most common types of liver tumors in dogs include hepatocellular carcinoma, hepatic adenoma, and cholangiocarcinoma.

These tumors may be caused by genetic factors, exposure to toxins, or other underlying medical conditions.

Treatment options for liver tumors in dogs may include surgery, chemotherapy, or radiation therapy.

It is important to note that prevention may not be possible for all cases of liver tumors in dogs, but owners can minimize their dog’s risk by ensuring they have a healthy diet, avoiding exposure to toxins, and scheduling regular veterinary check-ups.

Early detection and treatment of liver tumors in dogs can help improve the prognosis and quality of life for affected animals.

6. Hepatic Lipidosis

Hepatic lipidosis, also known as fatty liver disease, is a common cause of liver failure in dogs. It occurs when there is an excessive accumulation of fat in the liver, which can lead to liver damage and dysfunction.

The cause of hepatic lipidosis in dogs is often multifactorial and may include factors such as obesity, diabetes, fasting, and certain medications. It can also occur as a result of other underlying liver diseases or conditions.

Treatment for hepatic lipidosis in dogs typically involves supportive care such as intravenous fluids, nutritional support, and liver protectants.

In severe cases, hospitalization may be necessary. It is also important to address any underlying conditions and ensure proper nutrition to prevent recurrence.

Prevention of hepatic lipidosis in dogs involves maintaining a healthy weight, avoiding prolonged fasting, and ensuring proper nutrition. Regular check-ups with a veterinarian can also help detect any underlying conditions early on.

7. Chronic Diseases

Chronic Diseases in dogs can lead to liver failure as a result of the damage done to the liver over time.

This damage can be caused by factors such as chronic hepatitis, Lyme disease, lack of exercise, canine parvovirus, dental disease, and leptospirosis, among others.

The most common causes of liver failure are hepatitis and other viruses, alcohol abuse, nonalcoholic fatty liver disease, and autoimmune diseases.

Treatment for liver failure in dogs depends on the cause of the condition and may include medication, surgery, or a combination of both.

Prevention of chronic diseases in dogs can be achieved through regular exercise, proper diet, routine dental care, and timely vaccinations.

It is important for dog owners to monitor their pets’ health and seek veterinary care as needed to prevent and manage chronic diseases that can lead to liver failure.

8. Autoimmune Diseases

Autoimmune diseases in dogs are a common cause of liver failure in dogs. They occur when the dog’s immune system attacks healthy liver cells, causing inflammation and damage.

Treatment for autoimmune liver disease typically involves the use of immunosuppressive drugs to reduce the activity of the immune system.

In some cases, surgery may be required to remove damaged portions of the liver.

Prevention of autoimmune liver disease is difficult, as the underlying cause is often unknown. However, early detection and treatment can help manage the condition and prevent further liver damage.

Regular check-ups with a veterinarian and monitoring of liver function can aid in early detection. Additionally, maintaining a healthy diet and minimizing exposure to toxins may help reduce the risk of developing liver disease in dogs.

9. Medications and Supplements

Medications and supplements for dogs can be a common cause of liver failure. This can occur when the liver is overwhelmed by the toxins present in certain medications or supplements, causing damage and potentially leading to liver failure.

Treatment for liver failure in dogs typically involves supportive care, including medications to manage symptoms and limit further damage to the liver, as well as dietary changes.

Prevention involves working with a veterinarian to carefully monitor the use of medications and supplements and avoid potentially harmful products.

It is important to always follow dosage instructions and consult with a veterinarian before giving any medications or supplements to your dog.

Additionally, keeping your dog up to date on regular check-ups and bloodwork can help detect any early signs of liver disease.

10. Obesity and Poor Diet

Obesity and poor diet are known causes of liver failure in dogs. Excess intake of fat can cause a build-up of triglycerides in the liver, leading to inflammation and ultimately liver damage.

Treatment for liver failure in dogs typically involves addressing the underlying cause, which may include a change in diet and weight loss for obese dogs.

In cases where liver damage is severe, supportive care such as intravenous fluids and medication to protect the liver may be necessary.

Prevention of liver failure in dogs includes feeding a balanced, healthy diet with appropriate portion sizes and maintaining a healthy weight through regular exercise.

Regular veterinary check-ups can also help detect and address potential liver issues early on.
