I'd be careful changing foods a lot. In a finicky dog, it can encourage even more pickyness. Silly babies.
I would keep feeding as long as she'll eat it and maybe provide her excitement with yummy treats, like little pieces of chicken or beef that you're eating. Just make sure you don't feed her too much or she won't eat her dinner. I mean, if I turned my nose up at a salad and someone gave me McDonalds, I'd keep trying my luck too!
If she won't eat it at all, that's a different story. Then you should try the old tricks of warm water on the food, or adding in a little rice, or maybe a tiny bit of chicken stock. Just remember, sometimes the more add-ons you use, the more ridiculous the whole process can get!
