I think a lot of people have the misconception that dogs have similar appetite and food frequency requirement as people. I know of people who panick if their dog doesnt get fed exactly at the same time everyday or when the dog "looks hungry".
Dogs who eat breakfast and dinner dont require snacks, lunch or bedtime food. So if you feed a balanced breakfast and dinner your pup shoudl be fine and shouldn't require a bedtime snack. If he gets proper meals at breakfast and dinner he shouldnt be hungry anymore.
