E-mail: dayanecaico@hotmail.com The Transmissible Venereal Tumor (TVT) is a round cell neoplasm mostly affecting the genital of dogs. They can affect both sexes, and most animals are sexually active. Metastases, which occur in less than 5% of cases, occur through lymphatic or hematogenous. Diagnosis can be made by cytology and the most effective treatment is chemotherapy with vincristine sulfate. This study reports the occurrence of TVT from January 2010 to December 2014 in the UFRRJ Veterinary Hospital at the Oncology sector; clinical records were reviewed: 1,522 animals were seen and 123 (8.08%) presented TVT. Of 123 animals afflicted, 71.54% were adults, 23.57% were senior and 4.87% had less than a year. A higher frequency of females (74) was observed, when compared to males (49). A higher incidence in mutts (78.05%) was found, followed by poodles (7.32%), pinscher and Labrador (3.25%). Genital location was most common (79.04%), followed by a genito-cutaneous presentation (8.94%), nasal (5.69%), cutaneous (5.69%) and ocular (0.81%). It can be linked with large quantities of stray dogs and poor animal control policies in the region.
