Yes I did check her food for being recalled and it wasn't BUT that was another reason for switching her food...She doesn't have tummy issues. 
She just seems board with the Natural Balance. I have found that the only way she will eat is when I hand feed her or if she thinks the other dogs are going to eat her food then she goes nuts. She kind of a bully when it comes to food.
  
 But today she has not wanted to eat anything but her chicken breast. And she in heat day 8 and she's a mess 

....I have noticed thast shes pretty calm during this time...and it's really hot here in lower Michigan right now. So maybe it's a combo of everything

..I don't know..I just wished she could tell me whats wrong
