Yes, my little girl has one the size of a dime. After a week of applying the apple cider vinegar it started to loose the outer skin, and looked very raw. It upset her, so I stopped using it. I am using coconut oil for a couple of weeks, but with no results. There are a couple of videos on YouTube, and they did state the wart would bleed. I am trying to work on her insides, and stopped sweet veggies like carrot and sweet potatoes. She is on a raw diet with added raw pulp veggies. It is pretty common in older small dogs. No sweets, no junk food, little high sugar veggies. Also started giving her salmon oil ( distilled, metals removed) and turmeric. May try the apple cider internally with her food too.
