I'm sure you know all the tricks of the trade being so experienced with dogs. But have you tried feeding her with another overzealous dog that likes to eat? Sometimes that'll coax a finicky eater into eating as (I think?) they fear the other dog may eat their food and don't want that to happen. Do you take away her food after about a half an hour? Also, sometimes I put a couple of treats or mix the food with a little bit of cheese. I put it at the bottom of the bowl and then cover it with kibble. Smokey has to dig it out and in the process begins to eat...
Just some of my experience...Hope it helps a lil
