Transmissible Venereal Tumors

 What is a transmissible venereal tumor?

This is a common tumor, only found in dogs. It is transmitted by direct physical contact. It occurs in both sexes and may appear as multiple subcutaneous nodules on the genitalia, lips and other parts of the body.{{more}}

Why has my dog developed this cancer?

The cancer is transmitted by sexual contact or direct contact with the infected tumor (e.g. by licking). Therefore, an infected dog transmitted this tumor to your dog through direct contact.

Is this a common tumor?

These are common tumors of dogs in St Vincent and the Grenadines, particularly in stray dogs.

How will this cancer affect my dog?

The tumors are nodules, sometimes multilobulated, often found on the penis or vulva. Most ulcerate and bleed. The tumors may spread through the body, and the dog may develop many tumors in the skin.

The tumors grow rapidly at first and then remain static for a time.

How is this cancer diagnosed?

Clinically, this tumor has a fairly typical appearance. Definitive diagnosis relies upon microscopic examination of tissue.

What types of treatment are available?

The most common treatment is surgical removal of the lump and/or chemotherapy.

Can this cancer disappear without treatment?

Yes, sometimes. This cancer grows rapidly at first and then remains static before the dog’s immune system produces specific antibodies that may cause the tumor to spontaneously regress. Once the tumor regresses, that dog is then highly resistant to further tumor implantation.

How can I nurse my pet?

Preventing your pet from rubbing, scratching, licking or biting tumors will reduce itching, inflammation, ulceration, infection and bleeding. Any ulcerated area needs to be kept clean.

After surgery, the operation site needs to be kept clean and your pet should not be allowed to interfere with the site. Report any loss of sutures or significant swelling or bleeding to your veterinarian.


Are there any risks to my family or other pets?

“Preventing physical contact between your infected dog and others is essential.”

A transmissible venereal tumor is transmitted from dog to dog. Preventing physical contact between your infected dog and others is essential. You should also wash your hands after handling your dog and disinfect anything that may be contaminated with living cells from your dog that could come into contact with other dogs. The tumor cannot be transmitted from dogs to other animal species or to people.
