my howie is 6 months old and i have him in the laundry room, from what i have read here on the YT wee-pads are a good training source. where they had howie they just had newspapers everywhere so he did buisness all over. we brought him home and automatically started the wee-pads! he seems to be doing good on them, we have more than 1 wee pad to find his "spot" to do his buisness and he usually goes on the wee pad closer to the door. so what we are going to do is gradually decrease the number of wee pads. i think you should train your sonia on wee pads if possible. but don't worry girl she will eventually get it, try blocking the entrance under your bed. don't feel like a bad yorkie mom .. i felt like that last night almost in TEARS
