Personally I would leave it be. She IS eating it. If you plead with her and switch foods or try adding things to it, you'll just create a finicky monster. We have costumers at work that have tried every single brand of food that we carry because they have dogs that will only eat something for a couple weeks, and then they stop... and then the owners cater to them and try a different brand. And eventually they have exhausted every option and they have to fight their dogs to get them to eat ANYthing. I'm sure she loves the canned food and she is probably trying to ignore the kibble for as long as possible, hoping that you'll give her canned instead
TOTW makes 4 different flavors so what you could do is rotate through those, and get a different flavor every time you buy a new bag. If you want her to get a variety or are worried about her getting bored. But do that on your own terms, not just because she turns her nose up at her breakfast... a healthy dog will not starve itself, so unless it has been over 24 hours since she last ate, I'd wait her out.
