Warts on dogs are similar to pimples that appear on the human skin. Warts appear as small skin eruptions that may occur anywhere on the body, including the face, paws and feet of the dog. These round skin growths are also seen inside the mouth and even near the eyebrows. Warts are sometimes described as 'harmless tumors', that can cause slight irritation in the affected part of the skin. However, dogs affected with warts neither appear lethargic nor do they show any signs of weakness.

Causes
Warts is considered to be a viral infection, and dogs that are exposed to the virus 'papillomas' are likely to show presence of warts on their skin. Older dogs are susceptible to warts as they have a weak immune system. The affected dog may either have one relatively big wart or multiple warts on the feet and the face. These benign skin tumors generally occur in small number and do not interfere with day-to-day activities of the dog.

Treatment
Honestly speaking, dog owners have nothing to worry about as in most affected dogs, these bumpy skin growth, diminishes on its own. A healthy dog diagnosed with warts will not require any topical treatment to get rid of skin infection. However, in order to remove warts fast, following are the treatment methods.

Medications: Dogs that have large number of warts on their skin are given anti-viral medications such as interferon to eliminate warts.

Vitamin E Oil: Vitamin E supplements (pills) are readily available at various drug stores. The pills contain natural vitamin E oil which needs to massaged on the affected part of the dog's skin daily. Within a few days, one will see substantial improvement in the appearance of the skin. Regular application of vitamin E oil will shrink the warts and eventually this viral infection vanishes.

Castor Oil: This home remedy can work wonders to get rid of warts on dogs feet. Rubbing small amount of castor oil twice daily on the infected part of the skin can cure warts. One can also use a cotton swab to apply castor oil and one will see amazing results within a week. Castor oil also helps to reduce the irritation of the skin.

Thuja: Warts on dogs paw can be treated with thuja. It is basically an evergreen coniferous tree and its extracts are very useful to treat warts. Thuja extracts having a potency of 30C are generally recommended and are given twice daily. This homeopathic remedy makes warts smaller than subsequently do not remain on the skin.

Cryosurgery: In case the warts are becoming a cause of great discomfort for the dog, the veterinarian may perform a cryosurgery in which a method is employed to freeze the wart. Generally liquid nitrogen is applied in order to freeze the affected part of the skin. The extreme temperature kills the harmful virus, responsible for causing this infection. After 3-4 cryotherapy sessions, the wart eventually falls off.

There have been instances where the affected skin turned malignant (cancerous) over a period of time. However, this is very rare, and studies reveal that in most cases, the infection stays for a short duration of time.
