I just today noticed a lump on Lyric's cheek, right near his mouth. It is like the size of a marble and firm. It rolls over easily when I manipulate it and doesn't appear to hurt him. I reached my finger inside his mouth, against his cheek to see if it was originating inside his mouth, as in an ouchie. That didn't appear to be the case. It seems to be within. So, tomorrow, first thing, I'll call the vet. I'm so nervous. Dobes are sooooo prone to cancer.
