I am so glad you are getting a Yorkie. We have 3 and honestly I remember that pooty training was a pain with the first one we got but she was so cute that we really didn't mind. I must say that my 2nd and 3rd one were much easier because they followed their siblings. I keep mine in a laundry room that is inside the house, it is large. I do not close the door, so I bought a gate at the pet store, this way they get to see what is going on in the house. They each have their crates in there, but I do not close the crate door. They do go in there to sleep.The crate comes in handy when small children come to the house and I don't want them mishandling my babies. Mine are home alone about 4 to 6 hours a day and they do fine

I recently got a camera installed in that room it is called a DVR and I can keep an eye on them from work or any place with internet access. Good luck to you
