Introduction - Integumentary neoplasias are common in domestic dogs, representing approximately 30 to 40% of all the tumoral affections in this specie. This study aimed at detecting the most frequent cutaneous neoplasias in dogs, as well as their biological behavior, correlating them to breed, sex and age, intending at characterizing the occurrence patterns concerning this illness in a sampling of patients, according to aforementioned identification criteria. Material and Methods - One hundred dogs taken ill by solitary cutaneous tumors, was attended on the surgery service of the Veterinary Hospital of Universidade Paulista and characterized pursuant breed, sex and age. All animals were physically evaluated and their respective lesions undergone to the histopathological analysis. Results - Among the studied dogs, 64 (64%) were purebred and from those, the most taken ill were Poodle (n = 14) (23%), German Shepherd Dog (n = 13) (21%) and Boxer (n = 8) (13%), respectively. Within 100 evaluated animals, 57 (57%) were female and 43 (43%) males; 46 (46%) presented age between six and ten years, 29 (29%) equal or above 11years and 25 (25%) up to five years. The micro-morphological study detected 81 malignant neoplasias (81%) and 19 benignant (19%), of which 42 (42%) were mesenquimal, 35 (35%) epithelial, 15 (15%) of round cells and 8 (8%) melanocytic. Conclusion - Through the obtained results, this research concluded that Poodle, German Shepherd Dog and Boxer breeds, females, with age between six and ten years were most taken ill by cutaneous neoplasias. It was noticed also that most of integumentary tumors were malignant and had mesenquimal origin.
