Abstract
A 4-year-old Basenji with glycosuria was brought to our hospital. Blood glucose was normal, but aciduria and metabolic acidosis were found; we diagnosed the dog as suffering from a specific hereditary disease, Fanconi syndrome, which was established later by genetic tests. Bicarbonate treatment was started and continued according to Gonto's management protocol of Fanconi disease. The dog's physical condition has been good since then, although mild metabolic acidosis and hypophosphatemia are still present.
