Picky eater over here

Hey guys, my girl has gone through almost every large breed brand of dog food there is from tractor supply and Kahoots. What she is on now she is tired of. She’s allergic to chicken so that doesn’t help. I’m kind of at my wits end with this. I’m in a tight spot right now and cannot complete feed raw so do not recommend that please. I know about it already. Looking for what your guys Danes eat?? Mine is 1.5 yrs old
