I would consider a fence or something. Maybe leave them inside while you're waiting for the bus? I don't know...I personally would never allow my dogs to do that...if they did that everytime I waited for the bus, then they would be locked up for their own safty. You should work them a little bit at a time when you're around, or when you know they won't/can't go anywhere. If they someday learn now to follow you, then you can maybe keep them out off lead...

My dogs aren't always reliable offleash. I allow them to run offleash, so long as it is away from any road.

I'm sorry if I'm still misunderstanding this.
