I have a small deer on my property I have known for years and can feed by hand. She has a lump below the ear and behind the jaw that has grown rapidly over the last week. I don't think it is a tumor or lumpy jaw but likely an abscess. May possibly be fusobacterium or Caseous lymphadenitis. Has anyone successfully treated an abscess like this or have a suggestion to help her. She seems in good spirits and acts normally but the bump continues to get bigger.
