Puppy Warts | What Are They?

Puppy Warts What Are They And What Can You Do About Them?

The term “puppy wart” is used to describe a benign tumor found on the surface of your dog’s skin.

They can look like little cauliflowers, skin tags, or even white blisters.

These warts are usually present in or around the mouth and on the chin, although occasionally they can appear on the ears, eyelids, and even between the toes.

They are caused by the Canine Oral Papilloma Virus.

The infection is transmitted via contact with the papillomas on an infected dog. This virus can only be spread among dogs.

It is not contagious to other pets or humans.


The good news is that normally nothing is needed to treat these. In most cases, warts will disappear over time usually between 1-5 months.

Occasionally however a dog may develop a large cluster of tumors that may make it difficult for the dog to eat or drink and these may need to be surgically removed or frozen off.

Mature dogs with mature immune systems rarely develop papillomas.
