Hepatomegaly

Contributor(s): Gerry Polton

Introduction

  • Hepatomegaly in dogs is typically recognized during presentation for non-specific signs such as weakness, lethargy and inappetence. These patients are sometimes jaundiced.
  • Causes: infectious and toxic causes are typically associated with younger animals while neoplastic and cardiac causes are seen more frequently in older dogs.
  • Treatment: definitive diagnosis is required to establish an appropriate therapeutic plan and to correctly assess the quality of response so that modifications to treatment can be implemented.
  • Prognosis: dependent on the underlying cause and ranges from excellent to hopeless.
