Chronic hepatitis in the dog

Chronic hepatitis in the dog encompasses a diverse group of liver diseases characterised by a mixed inflammatory infiltrate within the hepatic parenchyma but with multiple causes. The aetiology is often unknown. Potential causes include hepatic copper accumulation, drugs, infections, and, speculatively, immune-mediated disease. Diagnosis is made based on liver biopsy. Treatment is predominantly supportive, while corticosteroids may be indicated in selected cases with idiopathic chronic hepatitis.
