I feed mine on Royal Canin, she is doing very well on it, I had to keep swapping around when she was a pup as she was a fussy eater. I also use a little Naturediet or raw mince to mix in with her complete as she can still turn her nose up at a bowl of dry food.
The only thing I might be slightly worried about with using just Naturediet, is there is no crunch to keep the teeth cleen.
If she likes it and is thriving on it, stick with it.
