Both of mine follow me everywhere, ALWAYS. If I'm sitting down, one is always on my lap and the other is right next to me. Sometimes they are both on my lap. If I'm up and moving, they follow me. If I get up in the middle of the night, Jake stays asleep in bed. He knows I'll be right back. However, Jackson will follow me, half asleep. He has to be with me at ALL times. Right now, one is on my lap and the other is sleeping with his head on my foot lol.
Yorkies get VERY attached to their owners.
