Sounds like you're both doing GREAT w/ home cooking, good for you! If she is eating much less kibble than before and higher protein (which is usually the case w/ homecooking), then she may need some supps.
I use Solid Gold's Bone Meal for the calcium (which they need w/ the added meat/protein) and I use a supplement that provides multi vit/mineral, probiotics, EFAs, digestive enzymes:
