I use cheese as a treat for training, probably not the best thing for your dog to be having with every meal to be honest. It isn't going to 'poison' your dog or anything like that but it is very high in fat.
Dairy has lots of calcium and protein which is all good stuff in moderation for dogs and humans, but I would limit the cheese giving.
My boy likes white fish with his meals as the smell drives him mad, maybe try that, you can get it frozen and feed it raw.
