If she is eating it and her condition is great then it can't be all bad, ask your vet and do some research yourself and you will soon see it seems there is always something doing the rounds about one food or another.
We have Zeke on Nutro large breed as it was the only one that his skin didn't flare up with and he hass thrived after trying Hills, Ekanuba and a few others as well, IMO just find the food that works for you and Molly and stick to it.
We add sardines and a supplement as well and he gets fresh fruit and veg as well as a bone every second day but that it what suits him in consultation with his vet. There are so many diets and so much advice out there that it is confusing sometimes but if you trust your vet (and I hope you do) just have a quick chat to them
