Liver disease in dogs is not talked about enough! Did you know? Dogs aged 8 years and above are especially susceptible to liver disease. Some dog breeds such as the Labrador Retriever are notoriously predisposed to chronic liver disorders. 

Liver disease is an umbrella term and it can refer to chronic hepatitis, liver fibrosis, liver cancer and endocrine diseases (diabetes and Cushing’s disease). Even thyroid issues in dogs (hyperthyroidism) can cause liver damage. 

So, how can you understand whether your dog is 100% healthy with no signs of liver disease? Also, how do you understand when your dog is showing signs of liver disease? What are the tests you need to do? What are the most advanced treatment options? 

Let’s find out!

What is Liver Disease in Dogs?

The image is a part of a blog on "liver disease in dogs" and is designed to explain why liver diseases are common in dogs. The image has a light background with faint illustrations of dogs and cats. At the top left corner, there is a logo with the text "vetic." Below the logo, there is a large pink banner with white text that reads, "Why are Liver Diseases in Dogs Common?" Underneath this banner, there is a black text statement: "The liver is prone to inflammation and damage due to its multiple roles." The image is divided into three sections, each with a numbered circle and a description: A blue circle with the number "1" and a beige box with the text: "Filters toxins from blood and supports digestion." A red circle with the number "2" and a beige box with the text: "Produces bile for digestion and bilirubin from old RBCs." A blue circle with the number "3" and a beige box with the text: "Absorbs excess fats, toxins, and unwanted minerals."

The liver is a filtering organ. In dogs, all the food, medicine and treats they eat, are broken down in their stomach and the blood vessels pick up the necessary nutrients, fats and even the toxins. This blood then goes through the liver where it is purified and the excess fats and toxins are absorbed by the liver. 

The liver also produces bile which is necessary for digestion and bilirubin from old and broken red blood cells (RBCs). 

The liver plays a big role in keeping the body free from unwanted minerals, metals, byproducts of medicines and toxins. However, that makes the liver incredibly susceptible to multiple issues including inflammation and damage. 

Signs of Liver Disease in Dogs

The image is part of a blog on "pregnancy in dogs" by Vetic. It features a central illustration of a sad-looking dog with a blue collar. The background is light with faint illustrations of various dog-related items and activities, such as bones, paw prints, and toys. The Vetic logo is positioned in the top left corner. The main title, "Signs of Liver Disease in Dogs," is prominently displayed in a red box at the top center of the image. The signs are listed in blue text boxes on either side of the dog illustration. OCR Text from the Image: Title: Signs of Liver Disease in Dogs Left Column: Jaundice Decreased appetite Weight loss Vomiting Right Column: Lethargy Frequent thirst Grey or yellow stool Ascites

Since the liver is a multi-functioning organ, the signs of liver disease can vary depending on the site that’s affected. 

The most common sign of liver disease in dogs is jaundice – the yellowing of the mucous membrane. A dog’s gums, eyes, ears and abdomen (skin) often turn yellow due to high levels of bilirubin in the blood. 

Hepatic encephalopathy is the next stage of liver disease. In this stage, neurological signs are often combined with signs of jaundice. 

The signs of liver disease in dogs may include –

  • Decreased appetite
  • Repeated vomiting 
  • Weight loss
  • Frequent thirst
  • Frequent urination
  • Grey or yellow stool
  • Ascites 

If your dog has been lethargic, vomiting repeatedly and not eating, you need to speak with the veterinarian. Almost all liver diseases begin with innocuous signs such as inappetence, lethargy and vomiting. 

What are the Different Types of Liver Disease in Dogs?

There are hundreds of conditions and diseases associated with liver health in dogs. However, we are listing the ones most common among the myriads of dog breeds in India. 

Liver diseases can be primary (the cause lies within the liver) or secondary (some other organ function is affecting the liver). 

Infectious Diseases of the Liver

The image is a part of a blog on "liver disease in dogs" by Vetic. The background is light with faint illustrations of pet-related items such as bones, paw prints, and veterinary symbols. The top left corner features the logo and name "Vetic" in red. The main title "Infectious Liver Diseases in Dogs" is displayed prominently in a red rectangular box with white text at the top of the image. Below the title, there are three sections, each highlighting a different infectious liver disease in dogs: Canine Hepatitis: This section has a blue oval background with white text that reads, "Highly contagious; affects the liver and eyes." Leptospirosis: This section also has a blue oval background with white text that reads, "Spread through water; impacts multiple organs." Fungal Infections: This section has a blue oval background with white text that reads, "Histoplasmosis and coccidioidomycosis." The image is visually engaging, with decorative elements such as pink virus-like shapes and various dog-related illustrations in the background, reinforcing the theme.

Infectious liver diseases in dogs is unfortunately common in India especially among the unvaccinated puppies. The leading cause of liver diseases include canine hepatitis and leptospirosis. 

Both of these diseases are hard to diagnose and treat irrespective of the age of the dog. Survival changes are very slim. 

Other infectious liver diseases in dogs include histoplasmosis and coccidioidomycosis. These are fungal infections resulting from the inhalation of the fungal spores. These are stubborn infections and require months of anti-fungal medications. 

Endocrine Disorders

The image is an informative graphic from a blog on "Liver Disease in Dogs," created by Vetic. The graphic is titled "Endocrine Disorders Affecting the Liver" and highlights three specific disorders: Diabetes, Cushing's Disease, and Hyperthyroidism. Each disorder is described with a brief explanation of how it affects the liver. The background features faint illustrations of veterinary-related items, such as bones and paw prints. At the bottom of the image, there is a concluding statement about the importance of treating hormone imbalances to improve liver health. OCR Text from the Image: Title: Endocrine Disorders Affecting the Liver Leptospirosis: Alters liver’s glucose metabolism and function Cushing’s Disease: Causes excess cortisol, damaging the liver Hyperthyroidism: Increased hormone levels strain liver tissues Conclusion: Treating the hormone imbalance often improves liver health.

Many hormonal imbalances can harm the liver in the long-run. Diabetes, Cushing’s disease and hyperthyroidism are the most common endocrinal disorders that cause liver disorders in dogs. 

Often, treating the underlying cause (hormonal imbalance) improves the liver function of the dog.

Liver Mass in Dogs

Multiple dog breeds are prone to various types of liver masses and liver cysts. Some liver cysts can be present from birth (congenital). While others can grow as the dog ages. 

Growing masses can put pressure on the functioning tissues of the liver causing inflammation and injury. Typically, surgical removal is a viable option if these masses are non-cancerous.

Liver Cancer in Dogs

Liver cancer in dogs is not uncommon, but they rarely originate in the liver (primary tumour). Liver is one of the favourite organs for cancer cells to metastasize and grow. 

In a majority of the cases, liver cancer begins as lymphoma, mammary gland cancer, hemangiosarcoma, mast cell tumours or cancer of the intestine. 

Vessel Abnormalities in the Liver

Most vessel abnormalities fall under the category of congenital portosystemic shunt. It is a birth defect where the blood vessel goes around the liver instead of going through. Liver shunt in dogs causes a build-up of toxins which can cause seizures, stunted growth and disorientation. 

Acquired liver shunt is only seen in older dogs caused by high blood pressure and cirrhosis. 

The only treatment is surgery, if there is only one or two large vessels present outside the liver. If the condition is not treatable, focus is given on the management of the condition. 

The image is part of a blog on "liver disease in dogs" and is designed to provide information about different types of liver diseases that can affect dogs. The background is light pink with subtle illustrations of dog-related items such as bones, paw prints, and fish. At the top left corner, there is a logo with the text "vetic" in red. Below the logo, there is a prominent heading in a red box that reads "Different Types of Liver Disease in Dogs." The image is divided into four sections, each with a blue header and pink content box. The sections are as follows: Infectious: Canine Hepatitis, Leptospirosis, Fungal Infections Liver Masses: Benign and Malignant Tumours, or Cysts Endocrine: Diabetes, Cushing’s Disease, Hyperthyroidism Vessel Abnormalities: Birth Defects or Acquired Liver Shunts OCR Text from the Image: vetic Different Types of Liver Disease in Dogs Infectious Canine Hepatitis, Leptospirosis, Fungal Infections Liver Masses Benign and Malignant Tumours, or Cysts Endocrine Diabetes, Cushing’s Disease, Hyperthyroidism Vessel Abnormalities Birth Defects or Acquired Liver Shunts

Breed-Specific Liver Disease in Dogs

Some breeds such as Doberman Pinschers are predisposed to a particular liver condition – copper storage disease. Breeds predisposed to copper storage disease are also prone to chronic hepatitis. 

The Shar-Pei breed is particularly prone to amyloidosis, which is the result of abnormal protein build-up in the liver cells. 

How is Liver Disease in Dogs Diagnosed?

The image is part of a blog on "liver disease in dogs" by Vetic. It features a header with the title "Diagnosing Liver Disease in Dogs" in a red box with white text. Below the header, there are three sections, each with a paw icon and a blue background. The sections are labeled "Blood Tests," "Imaging," and "Liver Biopsy." Each section provides specific information about the diagnostic methods: Blood Tests: "Liver enzymes, bilirubin, and kidney parameters." Imaging: "X-rays and ultrasounds show liver size and shape." Liver Biopsy: "Confirms cancer, abnormal cells, or copper deposits." To the right of these sections, there is an illustration of a dog lying down under a surgical light. At the bottom of the image, there is a note in black text: "These tests help determine severity and best treatment options."

If a dog is showing all the clinical signs of liver diseases or jaundice, your veterinarian will recommend immediate blood and biochemistry tests. Without learning the reports of the Complete Blood Count, liver enzyme levels, bilirubin content and kidney parameters, any treatment provided can only be symptomatic. 

Your veterinarian may also want to rule our Cushing’s and hyperthyroidism to get close to a differential diagnosis. 

Abdominal X-rays and ultrasounds are also recommended in the cases of jaundice and similar signs to understand the health, shape and size of the liver. They can reveal abnormalities including masses and tumours on the surface of the organ and its surrounding.

In the cases where nothing conclusive is known from blood and biochemistry tests, imaging and USG, the veterinarian may recommend a liver biopsy. Apart from checking for cancer cells, a biopsy can also reveal if a dog has other unusual cell structure or copper deposits in the liver.

Treatment of Liver Disease in Dogs

The image is an informative graphic from a blog on "liver disease in dogs" by Vetic. It features a veterinarian examining a dog, with text detailing the treatment options for liver disease in dogs. The background is light with faint illustrations of pet-related items. The main text is in a large pink box, with three treatment options listed below in smaller pink boxes. Each treatment option is accompanied by a brief description. At the bottom, there is a note about the importance of regular monitoring. OCR Text from the Image: Header: "vetic" "Treatment of Liver Disease in Dogs" Treatment Options: "IV Fluids: Restores hydration and electrolyte balance" "Medications: Liver support, antibiotics, or antifungals as needed" "Diet Modification: Low protein, high carbs to reduce toxins" Footer: "Regular monitoring through blood tests and check-ups is mandatory"

The treatment of liver disease in dogs will depend upon the signs and significantly upon the test reports. While some diseases can be cured comparatively easily, others have guarded prognosis depending on the severity of the disease. 

Chronic liver diseases such as cirrhosis of the liver or metastatic cancer have poor prognosis. If any dog is diagnosed with chronic liver diseases, their treatment is often limited to management and slowing the progression of the disease. 

The common treatments given for liver diseases include –

  • IV fluids (depending upon their temperature and electrolyte requirements)
  • Liver support medication
  • Antibiotics (if it’s a bacterial infection)
  • Antifungals (if it’s a fungal infection)
  • Toxin binders 
  • Vitamin E and K

Your dog’s diet may be modified to suit their health and recovery process. In the cases of jaundice or liver issues, the veterinarian can recommend high carbohydrate and low protein food to reduce the toxins in the blood. 

Regular monitoring is necessary for any type of liver disease. Frequent blood and biochemistry tests are necessary to understand the improvement of your dog’s condition. 

How Can You Prevent Liver Disease in Dogs?

The image is a part of a blog on "Preventing Liver Disease in Dogs" by Vetic. It features a header with the Vetic logo and the title "Preventing Liver Disease in Dogs" in a bold, red banner. Below the title, there are three key points listed with corresponding icons and descriptions: Vaccination: Represented by an icon of a syringe and a dog. The text reads, "Yearly shots against hepatitis and leptospirosis (9-in-1)." Regular Vet Check-ups: Represented by an icon of a clipboard with a medical cross. The text reads, "Twice-yearly visits track health changes." Balanced Diet: Represented by an icon of a bowl with food. The text reads, "Supports liver function and overall health." On the right side of the image, there is an illustration of a veterinarian in a blue coat, holding a stethoscope and examining a dog. The background is decorated with faint, playful illustrations of various pet-related items and symbols.

Not all liver diseases in dogs are preventable. Nonetheless, you can reduce the risks by getting them vaccinated against hepatitis and leptospirosis (part of the 9-in-1 vaccine) on time and repeat the doses yearly. 

Take them for veterinary check up at least once in 6 months so you can keep track of their changing health parameters. 

Early diagnosis is the key to a better prognosis.
