Frecuencia del tumor venéreo transmisible en perros de las parroquias urbanas y rurales en el cantón de Cuenca

Abstract

The frequency of canine transmissible venereal tumor (CTVT) was studied in dogs from urban and rural parishes of the Canton of Cuenca, as well as its relationship with risk factors. 412 dogs were sampled, with 36 positive cases of CTVT (8.74 %) and 376 negative cases (91.26 %). Samples were taken by swabbing and fine-needle aspiration of the prepuce, vagina, and extragenital lesions, which were analyzed through cytopathological and histopathological studies.The frequency of CTVT was 77.78 % in young adults and 22.22 % in older adults. Males and females showed a frequency of 50 %, and mixed-breed dogs had a higher frequency (63.88 %) compared to purebred dogs (36.12 %). Reproductive status and ownership turned out to be significant risk factors. Intact dogs had a 3,7 times higher risk of developing CTVT compared to neutered dogs, while dogs living outside the home had a 2,71 times higher risk. Tumor location was also significant, with genital tumors being almost 6 times more frequent than extragenital ones.Therefore, reproductive status, ownership, and tumor location are significant risk factors for the development of CTVT in dogs in the Canton of Cuenca. The importance of implementing prevention strategies is highlighted, especially in rural areas and for dogs living outside the home, as well as raising awareness among owners to improve the health and well-being of the canine population in the region
