Golden shepherd?

We’ve been trying to figure out what our dog is. Not for any real reason.

This is my baby Lilly and a vet said she is pure bred? Some German Shepherds can have lighter fur I guess. But we have no idea where she came from. I got her from a teenager who adopted her from a shelter and decided she didn’t want to take care of her anymore. When I got her adoption papers they say German Shepherd mix.

I think she’s a mix.

Then we randomly started looking and we think she might be a golden retriever and German Shepherd mix

What do you think?

Either way she’s cute as shit and the most well behaved dog I’ve ever had
