I'm glad the spaying went well for Sadie. I would stick Sadie on a strict schedule now and then stay with it in the new house.
I just posted this as an example of a strict potty schedule. It's similar to what I used with Sydney and it worked great. I used the crate method as explained in the book, "How to House Train Your Dog in Seven Days." It worked great.

And this is just my opinion, but you might want to still watch Sadie in the backyard. I've read about too many horror stories of predators taking off with Yorkies (the wild and human kind).
Good luck with the move. It sounds like an exciting time.
Sincerely,
Sonya
