Guess this puppy!!

My husbands parents had a stray come up to their house that was pregnant. They decided to keep her and help her with her puppies!!

Fast forward a couple of months ===> we decided to take one of the puppies!! We don't know what the daddy dog is at all but I will attach a pic of the mommy.

Does anyone have a guess of what our puppy could be a mix of??

Our puppy when we first brought her home to the most recent picture I've taken (her ears are quite big and the only one of the puppies to have the ears be completely up and be a darker coloring!)
