Is she outdoor or potty pad trained? I've always potty pad trained my yorkies and used an x-pen (playpen) type set up with a bed at one end (with toys & water too
) and potty pads at the other end, when she was a very young puppy.
My ZoE has had the run of the house since she was four months old and the potty pads are down the hallway outside the bathroom. She uses those during the day when I'm gone. She's one now and I have no issues with her going anywhere else in the house but on her potty pads.
