The liver is an essential organ for dogs, responsible for digestion, blood clotting, and toxin removal. However, dogs can develop liver disease, which can have various causes, including aging, genetics, infections, trauma, certain plants and herbs, untreated heartworms, diabetes, and issues with the pancreas.
Detecting liver disease in dogs can be challenging as the symptoms often mimic other health problems. Common indications of canine liver disease include loss of appetite, weight loss, vomiting or diarrhea, increased thirst, unstable walk, increased urination, confusion, jaundice, weakness, blood in urine or stool, seizures, and ascites.
If left untreated, liver disease can progress to hepatic encephalopathy, a severe brain condition. Therefore, it is crucial to work closely with a veterinarian, who may conduct blood tests, X-rays, ultrasounds, or biopsies to diagnose and assess the extent of liver damage.
The treatment of liver disease in dogs may involve dietary changes, supplements like SAM-E or milk thistle, antibiotics for infections, medication adjustments, or surgical removal of tumors or cysts. It is also important to take preventive measures, such as regular check-ups, vaccinations, avoiding harmful substances and foods, and maintaining a healthy weight for your dog.

Causes and Types of Liver Disease in Dogs
Liver disease in dogs can have various causes, and understanding them is crucial for effective treatment. Some common causes of liver disease in dogs include:
- Infections: Bacterial, viral, or parasitic infections can contribute to liver disease.
- Toxins: Exposure to toxins such as certain medications, chemicals, and plants can damage the liver.
- Poor fluid flow: Conditions that obstruct blood flow or bile flow into the liver can lead to liver disease.
- Hypoxia: A lack of oxygen supply to the liver can result in liver damage.
- Drugs or chemicals: Certain medications or chemicals can be destructive to the liver.
- Excess heat exposure: Prolonged heat exposure or heat stroke can cause acute liver failure.
Liver disease can progress through four stages:
- Abnormal inflammation: The initial stage involves abnormal inflammation in the liver, which can often be treated with medication or dietary changes.
- Fibrosis: Fibrosis occurs when the liver starts to scar and harden. If detected early, fibrosis can be reversed.
- Cirrhosis: Cirrhosis is characterized by permanent scarring of the liver.
- Liver failure: In the final stage, liver failure occurs, where the liver can no longer function properly.
In addition to the primary causes and stages, there are secondary conditions that can contribute to liver disease in dogs. These include vessel abnormalities, endocrine diseases, infectious diseases, liver masses, and liver cancer.
To ensure a successful outcome, early diagnosis and treatment are crucial. Treatment options for liver disease in dogs may include:
- Medication to address underlying causes and symptoms.
- Low-protein diets to reduce the liver’s workload.
- Vitamin supplements to support liver health.
- Lactulose, a medication that helps bind toxins in the gut.
- Antibiotics to treat infections.
- Symptom management to alleviate discomfort and improve the dog’s quality of life.
It is important to work closely with a veterinarian to develop an individualized treatment plan based on the specific type and severity of liver disease in a dog.

Diagnosing Liver Disease in Dogs
When it comes to diagnosing liver disease in dogs, veterinarians utilize a combination of diagnostic tests to assess liver values, identify abnormalities, and determine the underlying cause of the disease. These tests help guide the appropriate treatment plan for the affected dog’s specific condition.
One of the primary diagnostic tools used is blood work. Veterinarians typically start with a serum chemistry panel to evaluate liver function and look for any signs of liver damage. This panel may include liver enzyme tests, such as alanine aminotransferase (ALT) and alkaline phosphatase (ALP), which can indicate liver inflammation or injury.
In addition to liver enzyme tests, other blood tests may be recommended to further investigate liver function and rule out other potential conditions. These tests may include liver function tests, Cushing’s or hyperthyroidism screening, and urinalysis.
In some cases, further diagnostic tests may be necessary to visualize the liver and assess its structure and overall health. Abdominal ultrasounds and X-rays are commonly employed to detect liver abnormalities, such as tumors, cysts, or signs of inflammation. These imaging techniques provide valuable insights into the condition of the liver and help veterinarians determine an appropriate course of action.
For more precise analysis, a liver biopsy may be performed. During a biopsy, a small sample of liver tissue is collected and examined under a microscope. This allows for a detailed assessment of the liver’s cellular structure, identifying any specific diseases, infections, or cancers that may be present.
| Diagnostic Tests for Liver Disease in Dogs | Description |
|---|---|
| Blood work | Assesses liver values, including liver enzymes and liver function tests |
| Abdominal ultrasounds and X-rays | Visualize the liver and detect abnormalities such as tumors or cysts |
| Liver biopsy | Collects a sample of liver tissue for microscopic examination |
Through a comprehensive diagnostic approach that may include blood work, imaging techniques, and liver biopsies, veterinarians can accurately diagnose liver disease in dogs and develop an effective treatment plan. These diagnostic tests play a crucial role in ensuring the well-being and proper management of dogs with liver disease.
Treating Liver Disease in Dogs
The treatment of liver disease in dogs is aimed at managing the condition and improving the dog’s quality of life. The approach to treatment depends on the severity of the disease and whether the underlying cause can be treated or cured.
Dietary Changes
One of the primary treatment options for liver disease in dogs is making dietary changes. A higher carbohydrate and low-protein diet may be recommended to reduce the workload on the liver. This type of diet helps provide the necessary nutrients while minimizing stress on the liver. It is important to consult with a veterinarian or veterinary nutritionist to create a customized diet plan for the dog.
Vitamin Supplements
Vitamin supplements, such as vitamin E and vitamin K, may be prescribed to support liver function and promote healing. These supplements help to replenish any deficiencies and support the dog’s overall health.
