Jun you are 1 smart little puppy. Some are very easy to potty train I got Lucky my Luci was an easy one to. She is now learning to go out side now, but will only piddle out there.She still comes running in side to her piddle pad to do number 2. Aren't Yorkies just the dearest little dogs? Luci makes my heart melt every time I look at her. Have a great day.
Anne/Luci.
