She is still quite young,so dont worry
I dont beleive in taping,I wont get tired of saying this..lol.I honestly think that if your puppys ears want to stay droopy,they will do so,no matter what you do to prevent it..but if they decide to stand,this will happen on its own.
I have 2 yorkies and have done nothing to help their ears stand (exept shaving
) and they both have lovley ears,not floppy at all.A friend of mine taped her yorkies ears for 2 whole months (on and off of course) and his ears are droopy,so I can only recomend patients and to keep the ears free of hair.If theyre going to stand they will,and any time now
