I also think they meant clipped as in clipping the hair. You don't have to clip Yorkies ears to get them to stand. My Rhapsody's ears looked like your baby's and all we did was shave the hair about 2/3 of the way down and up to the top (inside and out), and then clipped the hair around the edges of the ears. When we did this her ears just popped up, we were prepared to tape the ears, but we didn't even have to!
Good luck -- do a forum search on taping the ears and that's where we got the instructions on how to do ours!
