Canine transmissible venereal tumour (CTVT), also known as transmissible venereal tumour (TVT) or Sticker’s sarcoma, is a transmissible cancer that affects dogs. CTVT is spread by the transfer of living cancer cells between dogs. This usually occurs during mating, but CTVT may also be transferred by licking, sniffing or parturition.
CTVT causes tumours which are usually associated with the external genitalia of both male and female dogs.
CTVT is usually treated with chemotherapy. Most dogs respond well to treatment and make a full recovery from the disease.
