Dolores har the hair on the top of her ears trimmed at 8 weeks by our breeder, but since they still made no attempt to stand at 11 weeks we were adviced to just cut down the hair (which grows really fast on her) again. So we did this and her left ear started standing up a few days later. Since her right ear still was down I cut her hair again two days ago (12 weeks) on just that ear and now it's standing up "part time", in a few days it will probably stand up permanently as the left one did.
So that's my advice. I cut the hair really close to the skin both on the outside and the inside on the top of the ear. But not so close that you can tell that they're not furry. They're still black/brown on the outside. Just use a good quality groomingscissor.
I was so happy not to have to tape them, I didn't think that trimming the hair would have such a great effect, but it did. Even when trimming with a week between there wasn't too much length to take off but it still made a difference in her ear.
Good luck to you! |
