A 3‐year‐old male Sheltie dog was presented with abdominal distension, diarrhea, and vomiting. Hematologic and blood chemistry studies revealed a mild anemia and a few leukocytes in the urine. Radiographic examination was made, and a large mass with calcified trabeculae was present in the ventral right cranial quadrant of the abdomen. Exploratory celiotomy was performed, and a mass identified as the right kidney was removed. The excised kidney was cystic and multiloculated, and contained areas of bone and cartilage. This mass weighed 1120 g and was in excess of ten percent of the dog's body weight. Transitional epithelium can stimulate osseous metaplasia. The presence of both tissues in a biopsy specimen might indicate urinary tract disease.
