Treatment of canine transmissible venereal tumors in a male dog through surgery and chemotherapy

Canine transmissible venereal tumors (CTVT) is a malignant tumor that affects the genital organs. It is highly contagious in dogs and is a significant global concern. This case report presents an effective and efficient treatment for CTVT in male dogs, offering valuable insights into veterinary care in small-animal oncology and surgery. A 2-year-old neutered male dog weighing 18,65 kg was examined by the owners, who reported the presence of a lump on the penis. The lump was initially small but increased in size over 2 weeks. In addition, the owners noted the presence of blood in the penis. Based on the anamnesis, clinical examination, and laboratory examination, the dog was diagnosed with CTVT with a good prognosis. Treatment included surgical excision of the tumors, followed by chemotherapy with vincristine sulfate. The postoperative wound completely healed within 7 days, and chemotherapy was administered 3 times with an interval of 7 days between each treatment. The dog was completely cured 1 month after chemotherapy without recurrence.
