They range in size from a small nodule (5 mm) to a large mass (>10 cm) that is firm, though friable. The surface is often ulcerated and inflamed and bleeds easily Canine transmissible venereal tumors (CTVTs), also called transmissible venereal tumors (TVTs), canine transmissible venereal sarcoma (CTVS), sticker tumors and infectious sarcoma is a histiocytic tumor of the external genitalia of the dog and other canines, and is transmitted from animal to animal during mating.It is one of only three known transmissible cancers in mammals; the others are. It also affects other canids such as coyotes, foxes and jackals. Also known as infectious sarcoma, venereal granuloma, transmissible lymphosarcoma or Sticker tumor, this disease is a benign tumor that occurs primarily on the external genitals of both male and female dogs. It is one of a very few tumors that can be transmitted by direct contact Canine transmissible venereal tumour (CTVT), also known as transmissible venereal tumour (TVT) or Sticker's sarcoma, is a transmissible cancer that affects dogs.
