"Canine warts, also known as fibropapillomas or papillomas, are usually painless and benign.  They tend to develop in the mouth (oral cavity papillomas) and on the superficial skin layers (cutaneous papillomas).  Warts in the oral cavity can cause discomfort, drooling and bad breath. Depending on where they are located, warts in the mouth can interfere with a dog\u2019s ability to grab, chew and swallow normally.  Warts on the skin often show up on the lower legs and feet, especially on the footpads and between the toes.  Warts in these locations can become annoying to the animal and cause it to lick and chew at the affected areas.  This, in turn, may lead to bleeding, pain and/or lameness and may predispose the dog to developing secondary bacterial skin infections."^^<http://www.w3.org/2001/XMLSchema#string>
