As far as the door goes I will never ever trust my dogs with an open door and they are from 1 to 10 years of age. No dog has road sense and the best trained one can be attractd by some movemetn and be off under a bus.
I have a baby gate on my kitchen to livign room door, and they are behind it if the door goes, and the livign room door is msotly closed, btu often because the ahll is small teh first person will o-pen the livign room door before the frotn door is closed.
For added safety I have also taught by dogs to wait at doors. It is quite easy you can sit them by the door and slowly open it while getting a stay command, if they lift their bums you close the door. Eventually they will reliably sit and stay when the living room door is open.
Next I have them sit with their leads on in the hall while I open the front door, and they must remain sat with front door open for increasing periods. I then move out the door holding lead at arms length and they must still stay. They are allowed through when I say come.
These steps have helped with the bolting for the door if anyone has not followed the house rules about the baby gate and doors being shut.
My Jozi first came back to me with that exact problem bolting out the door and running around the village she used to live in. It has contributed to her unreliability off lead (she bogs off every now and then) and she is 8 years old.
Despite the house rules she gave my old enough to know better kids the slip when I was at the Vets with another, and bolted up the street. We live on a very busy road with a bus route.
