From personal experience I would guess she cut her gums on her bone. Our dog did that with hers and she still kept chewing I had to have her give it to me or she would have kept scratching up her mouth. I am guessing she has lost all of her teeth? Our dog also had that happen when she would chew on something and lose a tooth, her tennis ball was covered in blood after that.
