Hello xxx

I am new here too. they are beautiful dogs, always wagging their tails.
I have two yorkies, Molly was a dream to train, Max was the opposite.

Take him out in the morning, and see if he will go to the toliet, lots of praise if he does. Inside i had some paper by the door, and would put them on as soon as they started acting like they wanted to go, or started to pee, and then praise like a lunatic.

Keep at it, and expect little mishaps. Plenty of praise .
