How contagious are dog warts?

Answered by Edward Huber

Dog warts, also known as viral papillomas, are a common skin condition in dogs. They are caused by a virus called the canine papillomavirus (CPV). It is important to understand that dog warts are not contagious to other pets or to humans. The virus can only be spread among dogs.

The transmission of CPV occurs through direct contact with an infected dog or contaminated objects. The virus requires injured skin to establish infection, which means that healthy skin will not be infected. This is an important factor to consider when determining the contagiousness of dog warts.

The incubation period for CPV is usually around 1-2 months. This means that after a dog has been exposed to the virus, it may take some time for visible warts to appear. During this incubation period, the virus is silently replicating in the dog’s skin cells.

Once the warts become visible, they can vary in size and appearance. They typically appear as raised, cauliflower-like growths on the skin. These warts can be found on various parts of the body, such as the lips, muzzle, eyelids, and feet. While they may look unsightly, it is important to remember that they are not harmful to the dog’s health.

It is worth noting that the contagiousness of dog warts decreases as the lesion progresses. Once the warts start to regress, they become less likely to transmit the virus to other dogs. This is because the virus is primarily present in the active and growing warts. As the warts start to heal, the virus becomes less viable and contagious.

It is always recommended to practice good hygiene and take precautions when dealing with a dog with warts. This includes washing hands thoroughly after handling an infected dog, avoiding direct contact between infected and non-infected dogs, and regularly cleaning and disinfecting any objects or surfaces that may have come into contact with the virus.

Dog warts are contagious among dogs but not to other pets or humans. The virus requires injured skin to establish an infection and has an incubation period of 1-2 months. It is important to take appropriate precautions to prevent the spread of the virus, especially during the active phase of the warts.
