Dog vaccine on trial as cure for melanoma in horses *H&H VIP*

Rosie Naylor MRCVS is a consultant in equine medicine at Newmarket Equine Hospital, where she sees a broad range of referred internal medicine cases in horses of all disciplines. She holds the ACVIM Diploma in Large Animal Medicine and recently completed a PhD at the Royal Veterinary College. She reports on a promising new therapy for melanoma, shown to increase survival rates in dogs, that could work for horses, too.

Melanomas are one of the most common tumours that affect horses. They are usually found in the skin,  particularly (but not exclusively) of grey horses. Affected horses typically develop firm, darkly pigmented nodules in characteristic locations — underneath the tail, around the anus, adjacent to the lips, on the sheath or in the throatlash region.
