Last night I noticed Champ has these small bumps on the top of his head between his ears. They are about the size of pimple but they are really hard. Its probably 6 or 7 of them up their but that is the only place he has them. They do not seem to hurt him and he doesn't try to scratch them or rub his head up against stuff to scratch them. I know for a fact they were not there sunday evening because I bathed him and I would have felt them when I washed his head. Has anybody ever encountered something like this? I tried to get pics but you can't really see them at all. I can just feel them when I'm petting him.
