I have an almost 8 month old that I restrict to the living, kitchen and dining area. I remove all stairs and shut bedroom and bathroom doors.
She does fairly well with potty but I still find things she or my older yorkie have peed on
I would love to restrict her even more, but this wouldn't be fair to Sugar, the older girl, and they are a very bonded pair. I also have all tile so it isn't too big of a deal if she has accidents. She does occasionally pee on the area rug or a blanket on the ground, however
