need ideas for preventing escape through front door— just moved into townhome on extremely busy road
edit: as stated below, we are still training. i just want a backup plan in the meantime as an extra precaution.
this is the set up of my new house. i have two pittie mixes that love trying to bolt out the front door— we live on a VERY major road (45mph+, 6 lanes, heavily trafficked, with a large bend right before our house (blind spot for oncoming drivers) and it is only about twenty feet from our front door. we are being extremely cautious and working on training them to stay away from the door but i want to have a backup plan in case they slip past us. does anyone have any ideas for a gate/fence/ anything i could set up as an extra precaution? i rent so it would need to be temporary but durable enough to contain two very strong pitties. it would also likely need to be exterior because there is no hallway or anything to attach a gate to inside- it opens up directly into the middle of our living room/kitchen area. any advice helps, thank you!!:)
