We don't have a fenced in yard, either. But we do have two, 25 foot cables...https://www.chewy.com/aspen-pet-x-large ... lsrc=aw.ds

We attach one end to a group of chairs (that are really heavy) and the other ends we keep inside, right by our back door (by the bells). So when they need to go out, we just attach them and out they go. When we were potty training them, I would still go outside with them while they were attached to the cables. This way, they don't run away.[/quote]

Hey! Something like that might work!
