I have a 6mo.old yorkie his ears only stand up half way. I shaved his ears but it didn't help that much. I have heard that while their teething they may not stand till after. I really have no clue if they have ever stood cause I got him at 5 and a half months. I have tried taping his ears but he's not going for that. I don't want to use duct tape or any thing that strong on his ears. Some say they should be up by 5 mo. and others say 10 mo. up to one year after that dont count on it. Anyone have thier pups ears stand late?
