Liver disease in dogs encompasses a range of conditions from acute toxic injury to chronic hepatitis, with dietary management playing a central role in supporting welfare and slowing disease progression.
Liver disease in dogs causes variable welfare impacts depending on stage and cause. Acute hepatic failure causes severe illness including hepatic encephalopathy — a neurological syndrome from ammonia accumulation causing disorientation, seizures, and coma. Chronic liver disease causes more gradual welfare deterioration including nausea, reduced appetite, abdominal discomfort from ascites, and loss of energy. Appropriate dietary management — feeding highly digestible protein sources, reducing copper intake in at-risk breeds, and providing antioxidant support — can significantly slow progression and maintain quality of life. Monitoring protein-responsive encephalopathy through observation of neurological signs guides dietary protein level adjustments.
