Could you post some photos? Some times in certain dogs, because of hair color and skin color, the area around the eyes appears somewhat bold. For example dogs with chocolate cinnamon color and almost pink skin look like this.

Not the best photos but peds are easy to copy paste compared to other photos. I have seen it in black dogs also.
