Abstract :
Osteosarcoma is the most frequent bone tumor in dogs representing about 85% of the tumors in bones. It’s occurrence in the axial skeleton is rare and it’s more frequent in females. The prognosis is poor with a great metastatic occurrence. A white shepherd dog, male, 8 years with a large tumor in the frontal region, quick growth, rigid consistency and pain by manipulation, was brought to the clinic. Surgical excision was performed and histopathological examination confirmed the suspected diagnosis as osteosarcoma. The patient was referred for chemotherapy. The tumor showed up again in the same location requiring new surgical procedure, but there was never evidence of metastasis in this case.
