Abstract
Hermaphroditism was discovered in four dogs at surgery. For the classification of the type of hermaphroditism in each case, gross morphological and histopathological studies were performed. Based on the histopathological studies, two dogs were diagnosed as unilateral true hermaphroditism because they had mixed gonad containing testis and ovary in unilateral gonad. Whereas two dogs were diagnosed as male pseudohermaphroditism because they had only testis and uterus that had endometrial atrophy. After resection, further follow-up of several months revealed no evidence of clinical abnormalities.
