Anther thing you can do is tohave other family members feed her. She we start getting more close to them as well if they take on more resonsibilty caring for her.
My Suzi does this with me. I could not even go to the bathroom without her trying to knock the door down! Sometimes, she was able to push the door open!
I love Suzi dearly. I never knew that yorkies could be like a little child though! very demanding, and clingy. I think that she probably spends more time with you the most as well, therfore she is very atttatched to you, and feel secure, safe with you.
