Liver failure
Liver failure is a serious condition that can occur in dogs. The liver is an important organ that performs many functions in the body, such as detoxifying waste products, producing bile, storing vitamins and regulating metabolism. If the liver fails, this can lead to serious complications and even death.
Causes of liver failure in dogs
There are various possible causes of liver failure in dogs, such as
- Infections caused by bacteria, viruses or fungi
- Poisoning by drugs, plants, heavy metals or other toxins
- Hereditary or congenital defects of the liver
- Autoimmune diseases that attack the liver
- Tumors or cancer of the liver
- Trauma or injury to the liver
- Ageing of the liver
Symptoms of liver failure in dogs
Symptoms of liver failure in dogs can vary depending on the severity and cause. Some common signs include:
- Loss of appetite or weight loss
- Vomiting or diarrhea
- Jaundice (yellowing of the skin, eyes or mucous membranes)
- Abdominal pain or flatulence
- Thirst or increased drinking
- Lethargy or weakness
- Changes in behavior or confusion

Diagnosis of liver failure in dogs
To diagnose liver failure in dogs, your veterinarian will need to perform a thorough physical examination and take a medical history of your dog. He will also order various tests, such as:
- Blood tests to check liver function and other parameters
- Urinalysis to look for signs of infection or kidney disease
- X-rays or ultrasound to assess the size and shape of the liver
- Biopsy or aspiration to take a tissue sample of the liver and examine it under a microscope
Treatment of liver failure in dogs
Treatment of liver failure in dogs depends on the cause and severity of the condition. In some cases, a special diet, medication or supplements may be sufficient to support liver function and relieve symptoms. In other cases, more intensive therapy may be required, such as
- Fluid and electrolyte therapy to stabilize fluid balance and blood pressure
- Antibiotics, antivirals or antifungals to fight infections
- Antioxidants, vitamins or amino acids to protect and regenerate liver cells
- Detoxifying agents to remove toxins from the body
- Blood transfusions or clotting factors to stop bleeding
- Surgery or chemotherapy to treat tumors or cancer
- Liver transplantation, as a last resort for severe liver failure
Prognosis and prevention of liver failure in dogs
The prognosis of liver failure in dogs depends on many factors, such as the cause, severity, age and general health of your dog. Some dogs may make a full recovery, while others may require lifelong support. In some cases, liver failure can be fatal.
To reduce the risk of liver failure in dogs, you should take some precautions, such as
- Keep your dog away from potential toxins, such as medications, plants, chocolate or rat poison
- Have your dog vaccinated and dewormed regularly to avoid infections
- Feed your dog a balanced and high-quality diet that is suitable for his needs
- Have your dog examined regularly by a vet to identify and treat potential problems at an early stage
- Have your dog neutered or spayed to reduce the risk of hormone-related liver disease
