The third presentation is cutaneous inverted papillomas , which has more in common clinically with intracutaneous cornifying epitheliomas. In this disease of young, mature dogs, lesions most commonly develop on the ventral abdomen where they appear as raised papulonodules with a keratotic center. Infrequently, viral papillomas in dogs may progress to invasive squamous cell carcinomas. These lesions are common, may be single or multiple, and can occur in any breed, but large breeds may be at an increased risk. Most commonly, they appear as pedunculated exophytic growths, often covered by a verrucous epidermal surface.
Treatment is optional, but a biopsy is recommended to confirm the diagnosis.
Acrochordons are amenable to excision, electrosurgery, and cryosurgery, but dogs that develop one are prone to develop others over time. After considering the above information cutaneous papillomas , could be a consideration, especially since an older Cocker Spaniels would be predisposed. Therefore, acrochordons sounds like a better possibility. The only way to know is from further examination. They put the colloidal silver on a cotton ball, then band-aid the cotton ball to the wart and leave on.
