Thanks, Sandra! It seems that the skin is ok, just the lips themselves are crusty. To me it seems like there's something going on in that area, though. Is there something called GSD Pyroderma? (not pyoderma)I've inquired on the GSD BB, too, cause I think I read something about that there. I didn't pay attention because I thought it was inside his mouth not outside. We may have hit on something. Or maybe he has both (sigh)!
