Here is my 2 cents worth. Yes they are work and yes you must do your homework. Research, talk here, and read. It should be agreeable with you and it sounds like you are halfway there. my husband and I both work and luckily my daughter comes and gets my baby. however she just started nursing full time and my neighbors daughter will be walking him and playing with him when she gets home from school. My husband was BIG TIME against me getting one, but he LOVES BEBE-I MEAN LOVES HIM!!! like a child. If you want it to work it will. Do not be scared & they are high maintenance but if you have love in your heart -you wont be sorry. You have to let go of the NEW FURNITURE< NEW HOUSE thing too. you have to keep an eye on them and train them to learn to potty outside or on pee pads. Bebe usually never pees in the house only has a pooh accident now and then and that is only if I ignore him when hes telling me he has to go. It is MY FAULT-not his. Patience, Love, and consistency (just like a child) I say you will be fine -Yorkie parents just need to be educated and self is no longer a word for you it must be family. Hope this helps
A yorkie will change you-I promise
