If you think your food isn't giving your pet enough nutrients you can also add a suppliment to thier food such as Nupro Gold Suppliment or Solid Gold Seameal. (I use the Seameal). This will ensure thier vitamins and trace minerals they need daily. It also has everything they need for proper digestion.
