E-mail: [e-mail] True hermaphroditism is an abnormality of gonadal development where there is genital ambiguity and ovarian and testicular tissues (ovotestis) in the same individual. In dogs, it is considered a rare alteration and there are few reports in the literature. Thus, we report a case of true unilateral hermaphroditism in an animal of the canine species, Cocker Spaniel, seven years old, indefinite gender and phenotype of both genders. It was attended was received at the University Veterinary Hospital presenting inflammation of the external genitalia and mammary tissue. For diagnostic elucidation and treatment were performed computed tomography, exploratory laparotomy with subsequent surgical resolution and anatomopathological and histologic examination. It was concluded that the animal had ambiguity in both, internal and external genitalia. Externally it was observed the presence of testicular pouch, primitives, foreskin and penis, rudimentary vulva containing hypertrophied clitoris. Internally, the reproductive system consisted of: prostate; uterus of which left uterine horn, partially hypoplastic, was in normal topography with its corresponding ovarian bursa, containing only ovary; the right uterine horn was in ectopic position, retroflexed, with a caudal orientation, passing through the right inguinal ring and inserting partially in the scrotum, in witch was found the right gonad. Microscopic evaluation of the right gonad showed the presence of ovarian and testicular tissue associated, characterized as ovotestis and confirming the diagnosis.
