Liver disease in the geriatric patient.

Abstract

Normal functioning of the liver does not seem to change significantly in dogs and cats as a result of age. Despite this, older dogs and cats are at greater risk for the development of liver disease. The diagnosis of liver disease is initiated by the veterinarian's suspicion that liver disease might be present, followed by the case history and a physical examination. The initial workup for the older dog or cat with suspected liver disease should begin with a CBC, serum chemistry profile, and urinalysis. This may be followed by a liver function test, radiographic or ultrasonographic imaging studies, hepatic fine-needle aspiration, and, ultimately, liver biopsy.
