Dogs, like people, can contract the papilloma virus that causes warts. Canine warts usually show up in older dogs and look like cauliflower blossoms. Warts are benign and, unlike other growths that may be cancerous, are usually light in colour. Take your dog to the veterinarian to be examined for any type of lump you feel under the fur. Based on a physical examination, the vet can determine how best to treat the warts.
Leave your dog's warts alone if he's been seen by a vet and the growths don't seem to bother him. According to the experts at Dog-Health-Guide.org, warts shouldn't hurt your dog (see Resources). If your pet doesn't notice the warts, no treatment is required. As warts are caused by a virus, sometimes the growths will disappear on their own over time.
Take a natural approach to treating irritation caused by your dog's warts. Rub vitamin E on the surface of the wart to soothe the dog's skin. Vitamin E capsules are available at most drugstores and supermarkets and can be broken open to use for this purpose.
Have your dog's warts surgically removed if she constantly licks or bites the affected area of her skin and gets no relief from vitamin E. This is a clear sign of irritation that can be resolved through surgery. Surgical removal of canine warts requires the administration of a general anesthetic.
Be on the lookout for changes to the appearance of the warts. If the growths begin to bleed or ooze, take your pet back to the vet for a second look.
