Hard to say, she seems like a real bitsa but I would say she has border collie and possibly kelpie in her somewhere. You will be able to tell better once she matures as her features will change. Congrats on the new family member!
Almost reminds me of a pharaoh hound... but those are pretty rare in most places. I could see her being a border collie mix, and agree with the other post that she may be part kelpie. It depends on the common breeds in your region though.
I'm 95% sure she's primarily a Pitbull Doberman mix but both parents were not pure pit and dob there's some Shepard in there for sure and possibly some lab and border collie. She should be an extremely loyal and protective dog. Congratulations
