The good news is that TVT is generally highly treatable when caught early. The most common treatment approaches include:
Primary Treatment
- Weekly vincristine chemotherapy (typically 4-8 sessions)
- Regular monitoring of tumor response
- Blood work to ensure proper dosing
Alternative Treatments
- Radiation therapy for resistant cases
- Surgical removal in specific situations
- Combination therapy approaches
Prevention Strategies
Preventing TVT requires a multi-faceted approach:
- Spaying and neutering pets

Can TVT in dogs be cured, and what is the prognosis after treatment?
Yes, TVT can be cured in most cases. The prognosis is excellent with proper treatment, and most dogs achieve complete remission. Early detection and treatment lead to the best outcomes.
How can I prevent my dog from getting Transmissible Venereal Tumor?
Prevention involves spaying or neutering your dog, avoiding contact with stray dogs, maintaining regular veterinary check-ups, and being cautious when introducing new dogs, especially from regions where TVT is common.
Understanding TVT symptoms in dogs and seeking prompt veterinary care when concerns arise is crucial for successful treatment. With proper awareness and preventive measures, we can help protect our canine companions from this transmissible cancer.
