Dog Chronic Active Hepatitis Diagnosis and Long-Term Care

Chronic active hepatitis is a progressive liver disease in dogs requiring early diagnosis and sustained treatment to slow progression.

Key Facts

Chronic active hepatitis (CAH) involves sustained hepatocellular damage with accompanying inflammation and fibrosis
Doberman Pinschers and Labrador Retrievers have breed-specific forms with suspected genetic components
Copper accumulation (copper storage hepatopathy) is a distinct form common in Bedlington Terriers and West Highland White Terriers
Diagnosis requires liver biopsy with histopathology and special stains for copper, iron, and fibrosis staging
Treatment includes SAMe, vitamin E, and ursodeoxycholic acid as antifibrotic and hepatoprotective agents
Low-copper diets are prescribed for dogs with copper accumulation and chelation therapy (penicillamine) is used in severe cases
Dogs with compensated hepatitis can maintain good quality of life for years with appropriate management

Welfare Considerations

CAH causes gradual liver function deterioration that leads to lethargy, reduced appetite, and eventually hepatic encephalopathy. Early detection through breed-specific screening and biopsy at the first sign of elevated liver enzymes allows treatment before advanced fibrosis develops. Management that slows fibrosis progression extends the period of good quality of life measurably.

What You Can Do

Request liver biopsy for definitive diagnosis in any dog with persistent unexplained liver enzyme elevation
Administer SAMe, vitamin E, and ursodiol as directed as hepatoprotective support
Follow dietary copper restriction recommendations for copper storage hepatopathy diagnoses
Monitor liver function and fibrosis staging every 6-12 months
Join liver disease support communities for guidance from owners managing long-term hepatic disease
