An eight-month-old, female Cocker Spaniel is presented because of a progressive enlargement of the clitoris which now protrudes from the vulval orifice. Examination shows that the vulva is small and somewhat cranially positioned. Palpation of the clitoris demonstrates that it has a central bone.

| What is the likely diagnosis? | This bitch is an intersex. The time of onset of the clinical signs corresponds with the onset of puberty and it is likely that there is androgen production by gonadal testicular tissue. Androgens (predominantly testosterone) cause clitoral enlargement and development of an os clitoris. Frequently there is excessive licking of the vulva due to lowgrade vestibulitis. |

| What is the aetiology of this condition? | Intersex animals may be classified according to the following three abnormalities:

| What are the treatment options? | The majority of intersex animals are infertile and surgical neutering is the preferred method of treatment. Following removal of the gonads, the os clitoris may become smaller as the animal grows and the clinical signs resolve. Clitoridectomy is mostly unnecessary but after puberty the clitoris may be large and require surgical removal. |
