Hi, i dont want ot start something, but you should leave your dogs ears alone. if acording to his breed standard his ears are meant to tip, or fold over, then that should be natural. if you have to manipulate them then i think that is the same as dying a dogs coat if it is the wrong colour for the breed!
my crossbreeds ears stood up when he was teething, and when he had finished they flopped over, as they are now, 2 years later.
