You can try different treats. If you take your pup to a pet store she might show some interest in certain brands
But, if that doesn't work her kibble is just as good as any treat. The idea is that you give your pup something to eat as reward- could be anything (as long as its okay for her health). Praise is a good reward. You can also use toys as rewards. In order to use toys as rewards you need to keep some of her favorites out of her reach, or it won't be special
