what do you do when your dog wont eat food that is good for him and wants the bad food. he hardly ever eats in the morn. and sometimes eats dinner just because he is so hungry , but will always eat a treat and had some of his old food left jsut tried that and of course ate that but a no go on his new food. the food he likes is purina beniful and i don't want to feed purina anymore becasue of the bad stuff in the food. Do we just go on like we are or what?
