| Abstract: | The clinical signs, laboratory findings and pathological changes are described in two cases of inherited copper toxicosis in the Bedlington terrier. The first case presented with acute signs of depression, vomiting, anorexia, weight loss and jaundice while the second case followed a more chronic course with less severe clinical signs which included weight loss and ascites. Both dogs had elevated circulating levels of alanine aminotransferase (ALT), however other haematological and biochemical parameters, while reflecting liver involvement, varied between the two cases. Chemical analysis of the liver revealed elevated copper levels in both cases (951·7 and 1093·4 μg/g wet weight respectively; normal less than 150 μg/g). These levels, however, are less than some affected but asymptomatic Bedlington terriers. Pathologically the first case had micronodular cirrhosis, while the second had focal hepatitis with fibrosis. Both dogs showed vacuolation of the white matter in the cerebrum, cerebellum, midbrain and medulla. Attention is drawn to the similarities and differences between copper toxicosis in the Bedlington terrier and Wilson's disease in man. |
