Transmissible Venereal Tumor in Dogs

Transmissible venereal tumors (TVT) are tumors that arise from the dysregulated growth of cells called histiocytes. Histocytes are a type of immune system cell found in many areas of the body, including the skin. TVTs develop from skin histiocytes. TVTs are malignant (cancerous) tumors. Different from other cancers, TVTs are transferrable between dogs. It is sexually transmitted through direct skin-to-skin contact with the tumor that results in cancer cells being transplanted from dog to dog. This type of tumor is more commonly seen in tropical and subtropical areas, particularly in Central/South American, the southern United States, Asia, and Africa, though it does occur world-wide. Dogs of any breed, age, or sex are susceptible, but it is most commonly observed in mixed-breed dogs, dogs that are sexually ‘intact’ (not spayed or neutered), and stray and free-roaming dogs.
