Finn has two growths under his tongue. They're each the size of a pea, though one is slightly bigger than the other. They're light, and cauliflower-esque. A friend told me they're warts, and that they'll go away on their own, but they've been there for a month and a half, at least. They haven't grown in that time, and they don't appear to be causing him discomfort. I'm thinking a vet visit is a good idea, but was wondering if anyone else has ever had this issue with their dogs? What causes it? Should he go to the vet, and if so, what treatment to they use for dogs? Thanks!
