In the present study, bone tumor samples obtained from 18 dogs and 21 cats from various clinics between 1986 and 2000 were clinically and pathologically examined at the Pathology Department, Faculty of Veterinary Medicine, University of Ankara. Most bone tumors examined were from 5-8-year-old dogs (43.75%) and cats (45%). A significant decrease was detected in animals over 8 years old. These tumors were observed in large breeds, mostly in German shepherd (38.4%) and Anatolian shepherd (Kangal) (15.4%) dogs. Tumors were seen in 10 male (66.7%) and 5 female (33.3%) dogs , and 11 male (61.1%) and 7 female (38.9%) cats. No information about the genders of the 3 dogs and the 3 cats was available. Of the tumors observed, 8 were benign (44.4%) and 10 malign (55.6%) in dogs, while 11 were benign (52.3%) and 10 malign (47.7%) in cats. Osteosarcomas were the most commonly observed malign tumors in dogs with 7 cases (38.9%), while fibrosarcomas (4 cases, 19%) and osteosarcomas (3 cases, 14.3%) were dominant in cats. Of the malign tumors observed, 2 had metastased to the lungs and kidney in dogs.
