Copper-Associated Hepatopathy

Copper-associated hepatopathy describes a pattern in which copper accumulates in the liver to levels that can damage liver cells. While copper is an essential trace element that all dogs need in small amounts, certain breeds and individuals may struggle to excrete it normally, allowing it to build up over months or years. This accumulation can eventually trigger inflammation, scarring, and loss of liver function. Owners often arrive at this possibility after routine blood tests show changes in liver enzymes, or when a dog develops signs such as reduced appetite, weight loss, vomiting, or jaundice. In some cases there are no outward signs at all, and the condition is identified only through screening or investigation of another concern. The presentation can range from subtle laboratory changes in an otherwise well dog to more advanced liver disease. This page explores the signals that may point toward copper-associated hepatopathy, the mechanisms by which copper damages liver tissue, the investigations used to measure copper levels and assess liver health, and the approaches that exist to manage copper burden and support liver function over time.
