Canine gonadal dysgenesis syndrome: a case of mosaicism (77,XO-78,XX).
A toy poodle bitch had an abnormal oestrus cycle and apparently persistent follicles. Hormonal therapy was unsuccessful. The bitch was ovariohysterectomised and gross and histological evaluation of the ovaries and uterus, together with karyotyping, led to a diagnosis of 77,XO-78,XX mosaicism.
