Introduction

Warts in dogs are not difficult to diagnose. They are typically visually observable, and owners tend to notice them and point them out to their veterinarians during routine annual check-ups.

How Canine Warts are Diagnosed

Papillomas in dogs are fairly identifiable just by their appearance. They can occur singly or in clusters, and often have a cauliflower-like appearance. They are common on the lips and gums, but also commonly occur on the dog’s lower legs (distal extremities). They look like what we refer to as “warts.” Basically, they are raised, lump-bumpy masses either singly or in clusters.

Advanced diagnostic techniques include biopsy of the mass and immunohistochemistry to identify the particular papilloma virus that caused the condition. Other protocols are polymerase chain reaction testing to identify the cause of cutaneous papillomas, and electron microscopy. Electron microscopy is usually used primarily for research rather than for clinical diagnostic purposes in pet dogs.

Special Notes

Sometimes, benign neglect is the treatment of choice for canine papillomas. However, owners should be aware of the highly contagious nature of this infectious condition. Canine “warts” are not simply a nuisance. They are caused by a virus that can easily be transmitted to other dogs by physical contact.
