What are warts in dogs?

Warts are going to be superficial benign tumors, that is, they will be on the skin of your canine, they are usually small, round and rough in appearance. Its appearance is due to the presence of the canine papillomavirus, which is one of the contagious diseases that we must avoid. The virus can be transmitted through direct and indirect contact and the virus can survive alone in the environment for several weeks, making it difficult to prevent infection.

Why do dogs get warts? Causes

As we mentioned previously, the main cause of contagion is the canine papillomavirus, however, below we mention other common causes to identify:

High contact areas

Warts often appear in areas where there is frequent contact between dogs, such as during play or in environments where multiple dogs share the same space.

Weak immune system

Dogs with weakened immune systems may be more likely to develop warts. This can occur in young dogs whose immune systems are still developing or in older dogs whose ability to fight infections may decline with age.

Genetic heritage

Some dog breeds may have a genetic predisposition to developing warts more easily than others.

Stress or illness

Stress and anxiety in dogs like certain other illnesses can affect a dog's overall health and, therefore, its ability to fight viral infections such as warts.

Types of warts in dogs

The different types and mutations of warts are created from two types of specific infections which are:

Cutaneous viral papillomatosis

This infection manifests itself on the skin in the form of warts or growths that are visible. Warts are usually small, round, and may have a rough appearance. Although they are usually benign, in some cases, they can cause discomfort if they are located in sensitive areas or if the dog scratches excessively. They are most common on the dog's head, neck, and legs. Infection is often seen in young dogs, as they are more susceptible to the virus.

Canine oral papillomatosis

Instead of manifesting on the skin, this variant affects the oral mucosa, giving rise to warts in the mouth, gums, tongue and surrounding areas. These warts can be more problematic and cause difficulty eating or drinking, especially if they are numerous or located in sensitive areas. It often goes away on its own as the dog's immune system responds. However, due to location and potential feeding complications, veterinary treatment is more likely to be sought in these cases.
