After giving a bath sometimes this happens, see when you give your pup a bath you are removing natural oils and this may cause the skin to flake, or it can be that it wasn't a good shampoo for the pup. Idk any "home remedies" i'll have to look into that but i can tell you that you need to stimulate your dogs skin so that the oil glands start producing the oils for the coat and skin.
All you need is a brush that has little rounded (usually plastic or rubber) ends, this will massage the skin and at the same time stimulate the glands.
Sorry i can't offer too much advice about this but try doing this for a while.
I found this thread, hopefully it can be more insightful.
