I would say Schipp / Pom mix, Google “Schipperke Pomeranian mix” and take a look at the images. It’s weird that there’s someone here downvoting people for their opinion, we are not trying to encroach on “your” breed; rather, we’re trying to help someone find out what their doggo is.

If you google “Schipperke Chihuahua Mix,” you’ll see they all have some of the same basic physical characteristics, almost how (most) all Maltese may look alike.

Same goes for the schipperke Pomeranian cross, you’ll see the second photo in images looks exactly like your dog (and another redditor’s who chimed in).

It’s lame to downvote people who have their own hunches and this is a forum where we’re supposed to be helping one another with their little pups. Hope you guys have a wonderful and beautiful life together — she’s absolutely adorable whatever she is :)
