i taped maggie's ears when she was 11 weeks old (if i remember right) and they stood up for a very long time. but as soon as she lost most of her teeth and they started growing back in, the ears flopped. i taped them for a day to see if they would come back up and they didn't. still floppy. i was told to leave them in for 3 days and see what happens. so i will probably do that, but if they do not stand this time, we will just leave them floppy. I really like the classic "yorkie" look so I want her ears to stand...but if they have to stay floppy, then so be it...she is precious and perfect to me either way. here is a pic of her down, and up. and they were REALLY up
for quite a while...now they are half up, the tops laying down. kinda cute tho
