Osteosarcoma is a malignant bone neoplasm with a high incidence in adult and giant breed dogs, with the appendicular skeleton being the most affected compared to the axial one. The symptoms usually present are claudication, swelling and may or may not be associated with episodes of fractures. The diagnosis consists of imaging exams, and in many cases, confirmation is only possible through bone biopsy. Due to aggressiveness the prognosis is unfavorable, and the best treatment for this case is limb amputation, with the intention of removing the primary tumor. The dog, in this report, was diagnosed by bone biopsy, whose histopathological result was osteoblastic osteosarcoma. The tumor originated in the distal femur of the left pelvic limb and the patient was referred for amputation, the surgical technique used was coxofemoral disarticulation. As an adjuvant treatment, chemotherapy with carboplatin was instituted. There were fivw sessions in an interval of 21 in 21 days, without reaction or alterations in the complementary exams. Pulmonary macro metastases were not identified in the radiographic examination, and a disease-free interval was observed, guaranteeing quality of life for the patient, despite being a very aggressive tumor.
