Severe jaundice and significantly increased ALP values were observed in a male Shetland sheep dog (13 years and 6 months old) brought to our hospital because of vomiting, anorexia, and weakness. Ultrasonography revealed gallstones and a spherical, slightly high-echoic mass approximately 2 cm in diameter near the gallbladder base. Laparotomy was conducted, and the gallbladder was bluntly separated from the liver parenchyma. The gallstones were removed. After checking the patency of the common bile duct, the gallbladder was removed. Pathological examination of the isolated tissue revealed that the mass in the gallbladder was hepatocellular carcinoma that had infiltrated from the liver parenchyma and protruded into the gallbladder lumen. Hematological and blood-chemistry examinations and abdominal ultrasonography conducted 190 days after surgery showed no abnormalities. Furthermore, no clinical abnormalities had been observed until more than one year after surgery.
