Clinical and pathological features of ovarian dysgerminomas occurring in two dogs and a cat are presented. The feline neoplasm had morphological characteristics closely resembling those of dysgerminomas in women. The feline and one canine neoplasm occurred in young animals as compared to other reported animal dysgerminomas.
