Playpan works great!! Make sure the one you get is tall enough thought. Yorkies are tiny but they sure can climb. When mine was 12 weeks old at 2 lbs, she climb out of a 20" tall gate. We got a 24" tall playpan afterwards and she learned not to climb out as we don't like it when she did. I am certain she can do it just as easily if she really wants to.
