Vaginal discharge in a spayed dog with multiple distinct malignancies.

BACKGROUND

An 11-year-old female spayed Labrador Retriever was presented with clinical signs of oestrus and vaginal bleeding. Historically, the dog had not cycled and had been spayed at less than 6 months of age.

RESULTS

Extensive investigation culminated in the diagnosis of an ovarian granulosa cell tumour. The patient had a history of localised grade III mast cell tumour 5 years prior and hepatic haemangiosarcoma 8 months prior to diagnosis.

CONCLUSIONS

Both conditions were successfully treated with a combination of surgery and chemotherapy and there was no evidence of metastasis or recurrence at the time of evaluation for signs of oestrus.
