What is my German Shepherd mixed with?

My dog's name is Keides. I got her off Craigslist.

I have been told she is mixed with Rottweiler, but no one knows for sure?

She has a good appetite, she is always hungry.

She gets quite a bit of exercise, likes to run and chase me, either I'm really fast, or she's slow lol.

She is a great dog, territorial! Likes to bite fingers a lot.
