Surgical and palliative management of a mammary carcinoma in a 9-year-old German shepherd

Canine mammary gland tumours (CMTs) are among the most frequently encountered neoplasms in intact female dogs, with nearly 50% demonstrating malignant behaviour. This case report delineates the clinical, diagnostic, surgical, and therapeutic management of a 9-year-old intact female German shepherd diagnosed with a bleeding, ulcerated mammary carcinoma with radiographically suspected pulmonary metastasis. Given the progression and clinical deterioration, a palliative unilateral mastectomy was undertaken. This report underscores the clinical relevance of palliative surgical intervention in advanced-stage-appearing disease and advocates for evidence-based, individualized oncological care in veterinary practice.
