Oh no they are mixed but I decided just one cup twice a day was not enough. So I up his food to two cups twice a day. I gradually added his new. Now he seems to be not crazy hungry as if he were starving like before. Next week it'll change again to 1 1/4 cup new and 3/4 old.. I've also noticed my older dog loves the wet brand better than the dry he must think its a Special Treat!!!
