Symptoms & types

Most of the time warts are nothing to worry about. Warty growths around the mouth of a young dog are usually caused by an oral papillomavirus, and the lumps regress by themselves again.

Understanding the diagnostics

Learning about the causes

Oral papillomas are contagious and can spread by either direct contact with an infected dog or through touching items that an infected dog has touched with their mouths (like toys and food bowls).

Best treatment options

You can support your dog by making sure he is on a good-quality complete diet to ensure his immune system is getting all the nutrients it needs.
