A twelve-month old female, shih-tzu, was presented to diagnose a hind limb ataxia to the Animal Teaching Hospital, Gyeongsang National University. Even though a variety of physical and neurological examination was performed, the cause of the ataxia was not understood. In serum analysis, an elevated levels of ALT, $\gamma$-GTP and LDH were found. A gallstone was subsequently observed at the right 9 and 10th intercostal region on ultrasonography and radiography. Cholelithiasis was diagnosed, and then cholecystotomy was undertaken. No complications were occurred after the operation. The gallstone removed by cholecystotomy was composed of calcium, carbonate and oxalate, identified by a black pigment gallstone.
