Hi, You might want to access IVIS, a compilation of veterinary presentations from meetings and journal articles. It is free. You can then do a search for "lick granulomas", tail injuries, etc. I know of cases where the dog has been sleeping next to the door on the inside and the owner opens the door from the outside catching the tail under the door. This can cause an slow healing injury. There are many possible explanations. Good luck.
