Abstract

Two American Cocker Spaniels and one Bichon Frise were presented to our veterinary teaching hospital with an enlarged clitoris. Diagnostic imaging showed that the structure was composed of bony material. Exploratory laparotomy revealed uterine-like structures and testes which had an epididymis unilaterally. Surgical removal of internal genitalia, gonads and protruded clitoris were performed well. Histological evaluation revealed; inactive testes, female internal genital tracts with ambisexual ductal remnants, and prominent ossification in the clitoris. All 3 cases were diagnosed with male pseudohermaphroditism. In author's knowledge, this is the first report in Bichon Frise dog with os clitoris and also, it describes not common cases in small dog breeds with os clitoris.
