ABSTRACT

Introduction. Transmissible venereal tumor (TVT) is a specific neoplasia in dogs that generally occurs in the mucosa of the genitalia. It is transmitted during coitus and is distributed world wide; stray dogs play an important role in the dissemination. The objective of this work was determine the prevalence of TVT in stray dogs captured at the municipal pound of Mérida and determine its frequency according to sex and age of dogs.
Material and Methods. A visual examination of 303 captured dogs was made after its sacrifice at the municipal pound of Mérida searching for neoplasias in the genitals. A frotis of the suspicious structures was made and were microscopically evaluated to determine its origin. Prevalence of the pathology and its frequency was determined according to sex and age of the animals.
Results. A prevalence of TVT was 2.64% (n=8) and was slightly larger in females (3.03%) than in males (2.18%); it was observed in animals 3 to ³4 years old.
Discussion. A low prevalence was probably found because of its slow dissemination among stray dogs or due to spontaneous regression. The sex of the animals does not seem to be an important factor in the dissemination of this pathology; adult to old animals seem to be more predisposed to acquire this pathology for being at risk longer.
