In general dogs without defined breeds had the highest number of cases. The age group had a predominance between nine and thirteen years, 81/256 (31.64%). Regarding sex, males obtained the largest number149 / 256 (58.20%). According to the biological behavior the benign and malignant had the same frequency 10/20 (50%).
