I notice KS wears a lot of clothes. If she is a true sot coated pup, you may want to consider a Joey cut to keep her comfortable and tangle free. She is still young and might be going through an awkward phase. Her hair looks a lot nicer than Kaji's in his awkward phase. He's a soft coated pup and nothing other than a short hair cut helped. His hair tangled even if you just looked at it. It was BAD!
I hope this helped even if it wasn't a brush review.
