Background: Canine transmissible venereal tumor (CTVT) is perhaps the oldest known canine neoplasia. It is spread by cell allogeneic transplantation among susceptible animals. It is globally distributed, mainly in urban areas with high populations of stray dogs. Objective: To estimate the current distribution and prevalence of CTVT in Colombia. Methods: After analyzing the literature, we obtained epidemiological information on CTVT from 152 veterinarians in five Colombian regions via an electronic form (using Google Forms). This analysis confirmed that CTVT is endemic in the inhabited regions of Colombia and is highly prevalent in the Andean region, the most populated region in the country. Results: For the reported cases of CTVT, no significant differences were found in terms of animal gender, reproductive status, or origin. An association was found between the number of CTVT cases and concomitant infectious diseases. Results also showed that vincristine is the most effective therapy for CTVT and resistance is not a serious problem in Colombia. Conclusion: Our results confirm that CTVT is endemic in the country, coinciding with global analysis of the factors that enable the continued existence of the disease, and implies that stray dogs are the reservoir. Accordingly, we recommend that canine control policies be introduced in Colombia.
