The more you practice with her ,the better she will get at sitting still. When we first got Bogie he wouldn't leave his alone and he would pull Jada's out too. I just kept putting his up and leaving it for a few minutes, and continued leaving it in for longer periods. Gradually he adjusted to having his up. Now he leaves his alone and his sissy's.
I also never leave them at home alone with clips or bows in their topknots, I am still untrusting of them getting them out and choking on them.
