Photograph of an 11-year-old Springer Spaniel with metastatic pulmonary lesions from mammary cancer causing hypertrophic osteopathy. Both front legs were swollen and painful due to hypertrophic osteopathy, which is associated with pulmonary metastases. The skin of the medial right foreleg is ulcerated with secondary infection. The bandage on the left hind leg is covering a fentanyl pain patch.
