A Yorkie or any Toy breed is like adopting a newborn child.
It takes how many years to potty train a 2 legged child?
It is a lot of work and praise and a lot of patience. Dogs want to please us so be sure to praise him when he does good.
Remember he has a tiny lil bladder.
A lot of toy breeds never go out to potty, they use potty pads or even litter boxes for the simple reason they are tiny and have to go more often due to their tiny bladders.
Do you have a room with tile floor where you can set up an expen for him with his pad in it until you can get him trained.
Have you tried putting a leash on him and around your ankle when you are giving him time to play in the LR.
Then you will know what he is doing and when he needs to go.
We have to learn the signs of he needs to go out to potty and when you have the leash on him and you, you can't miss the signs.
Alot of Yorkies will go under furniture to potty where no one sees them.
Best of luck
