Big Brain little skull...NO just joking! She looks like a dog someone spent money on cropping and docking , heavy Dobe , but come on do you really care.she looks smart and healthy. I have seen that "forehead" lump on more than one dog, usually when say a big headed mastiff gets sick and loses weight it becomes more pronounced, but  in all honesty I think its more of the angle of the shots her side shots do not show it and only direct on shots..if her ears were Straight up I bet your eyes would not notice the line is in perfect harmony with her eyes nose and ears..get a head on shot of a red dobe side by side and see if I am right.I think its a matter of her growing also.

Breeds  a lot of Dobe. maybe mom all dobe and dad was a lab/pit mix or one of those with a Dobe. Regardless she looks very nice and you are both lucky to have found each other.
