Adopted German Shepherd mix puppy

I recently adopted Sadie from a high kill shelter. The foster mother did not know what she was mixed with and after searching for many many hours, I still am not sure.

She is 3-4 months old and is still fairly small. She weighs 15 lbs.

She likes to explore all over my house is a good listener and is fairly reserved and submissive. She's curious, easy going, playful, and so loving. She is very observant over her surrounding (sounds/smells). Her ears still stand upright.

I was maybe thinking she was a terrier mix. But I have NO clue. Please let me know if you have any thoughts.
