I don't want to scare you but I just took my dog in Monday for what they too thought was that wart. My dog was fine with it but I noticed it. My doctor to be safe biopsied it and he is having surgery tomorrow to remove it as there are abnormal cell, they are thinking cancer but not sure type etc. I am scared to death but so thankful I had it biopsied. If you did not please think about having it done. |
