just put some chciken broth over her kibble. Works wonders for mine. She was the same and I smelled her kibble and realized..it smells like nothing.! Who would eat that? So I boiled a couple breasts and skim off fat and put one tablesppon over her food. Since she hasnt eaten you could do canned low sodium but I wouldnt do that all the time..
fyi My dog is a shaker..its not from being hungry either..shes a little piggy
