Sorry I'm not going to be able to help. I just wanted to add a comment.
Yorkies
love laps. They can't get to laps without getting on the couches. It's a losing battle in my house I'm afraid, but good luck to you. My previous dog (much bigger than a yorkie) was well trained and
never got on to the couches. I've given up on the yorkies. When I sit, they are instantly on my lap! Luckily they are small & don't shed.
