Hmm... could it be similar to herpes of the eye? I don't know?

My friend's Border Collie pup had a wart on her lip, that continued to grow and grow. It was also described as a viral wart, probably from contact with other dogs. She went to the Vet, they simply aspirated it with a needle, and it hasn't come back (yet). I suppose it would be much harder to do that when the wart is on her eyelid. Is it irritating her eye at all? If not, I would just try not to worry about it and hope that it goes down.
