Copper Toxicosis (Type ATP7B)

Overview

Copper toxicosis (Labrador retriever type) is an inherited metabolic disease affecting dogs, resulting in chronic liver failure. Dogs with copper toxicosis have a decreased ability to excrete dietary copper from the body resulting in excessive copper storage in tissues and organs, including the liver, which can result in liver damage and subsequent cirrhosis.

Characteristics and Symptoms

Most dogs that are affected are middle aged with non specific signs of liver dysfunction including weight loss, lethargy, weakness, vomiting, diarrhea, and abdominal pain. In late stages of disease, affected dogs may develop signs of liver failure including abdominal swelling, jaundice, and neurological dysfunction.
