Welcome and congratulations on your new Yorkie.
I don't know about most of your questions but consider the climate you live in, in the winter months it's a pain to stand out in the weather, rain or snow, waiting for them to do their business. Yes they just sniffed that spot ten minutes ago and now it's ok to pee on??????? I wish Buddybear was trained to use the pee pads when he balks at the door telling me he doesn't want to go out in this (like where is the sunshine).
I have a friend that untrained her yorkie mix to only go outside and she is sorry she did.
As a senior of 12 I think the least changing you do would help her adjust to the new situation.
