The ears of most Yorkies will stand upright by 6 to 8 weeks of age, but some take a little longer and some need a little help. Larger ears will usually have more difficulty standing, but don't give up--at least not until he's 6 months old. You can help train ears to stand by giving them some support. Begin by carefully shaving away the hair on the top third or half of the ears. both front and back. Be very careful. Next use masking tape to tape the ears so that they are folded in on themselves vertically and come to a point at the top. It will take a few tries before you it tight enough to withstand his pawing at it, but not so tight that it cuts off his circulation. Err on the side of too loose and plan on doing it again--and again. You may also tape the two taped ears together so that they stand up right. Remove the tape after 3 days {or anytime it gets wet} If the ears are standing, leave them alone. If not, tape again . Continue until they remain standing.
