My black lab was suffering w/increased liver enzymes and nothing the Internal Medicine Specialist did seemed to help. Then one day he said we could try Milk Thistle. He told me what % of Silymarin he needed and calculated the dosage for his weight. Shadow has been doing well ever since! You'd think I had a young lab again instead of a 9 year old!
