Panzer is 7 months old, and I first noticed one of these on his tongue about a month ago. Since then, a cluster has appeared. They are hard when I touch them. I've done some looking online and I think they might be canine papilomas, but haven't seen the vet to confirm. What do you guys think? And if you've had a dog with papilomas, did you do anything special to help them clear up? So far what I've read is eventually they go away after the dog builds an immunity to the virus and it won't be a problem anymore.
