Soft tissue sarcomas are often detected as a firm mass located on the trunk, limbs, or oral cavity. The symptoms depend on the tumor's location and degree of invasion. For example, tumors in the gastrointestinal tract may cause vomiting, diarrhea, or weight loss. Tumors in the mouth may cause bad breath, difficulty swallowing, or lack of appetite.
Osteosarcoma is the most common bone tumor in dogs and typically affects middle-aged large and giant breed dogs such as Irish Wolfhounds, Greyhounds, German Shepherds, Rottweilers, mountain breeds (Great Pyrenees, St. Bernard, Leonberger, Newfoundland), Doberman Pinschers and Great Danes. It has a 10-fold greater incidence in dogs than humans. [33]

Typically, clinical signs are due to hypovolemia after the tumor ruptures, causing extensive bleeding. Owners of the affected dogs often discover that the dog has hemangiosarcoma only after the dog collapses.
Kiupel and coworkers therefore proposed a new system with only two grades: low-grade and high-grade. Tumors are judged to be high-grade (high grade, malignant) if one or more of the following criteria are met in ten fields of view at high magnification (objective 40x): [23] at least seven mitoses
Untreated dogs have an average survival time of 60 days. [20] Lymphoma with a histologic high grade generally respond better to treatment but have shorter survival times than dogs with low grade lymphoma. [6] Dogs with B-lymphocyte tumors have a longer survival time than T-lymphocyte tumors. [1]
Dogs can develop a variety of cancers and most are very similar to those found in humans. Dogs can develop carcinomas of epithelial cells and organs, sarcomas of connective tissues and bones, and lymphomas or leukemias of the circulatory system. Selective breeding of dogs has led certain pure-bred breeds to be at high-risk for specific kinds of ...
