What condition does 'icterus' indicate?

The term 'icterus' specifically refers to the yellowing of tissues, particularly the skin and mucous membranes, which is primarily caused by an accumulation of bilirubin in the blood. This condition is often associated with liver dysfunction, hemolysis, or diseases affecting the biliary system. Because icterus is a clinical sign that reflects underlying health issues, it serves as an important indicator for veterinarians when assessing a dog's overall health or diagnosing specific conditions. Understanding this term is crucial for recognizing potential problems in canine patients and guiding appropriate diagnostic and treatment protocols.
