re: Finicky eater

Has your dog been spayed? If she is still intact she may be coming into heat and that will throw her off her feed. Heat, stress, changes can all affect a dogs appetite. If you are feeding a quality dog food I would leave off the extras and give her 3 days to give in and eat. It can take that long for them to decide there isnt anything else coming. Adding treats to their meal sometimes makes a picky eater. Of course this is assuming that she isnt acting like she feels bad, running a fever or generally acting like a sick baby.
