Lilah is pretty good at sitting, staying and pouting when I tell her to while I walk out the house to go to work etc but she can feel when I am debating taking her or leaving her and knows when I don't mean it as much (ack!) and will go out, again that good girl will tip her head down turn tail and walk back in the house when I point and tell her to go back in but one thing that solidifies my decision to keep a baby gate at my front door still- and I do- is that when I am outside of the house and someone else goes in or out the door and she really wants to hang out with me- regardless of whether I might be weed whacking or mowing the lawn
she will dash out to come find me. So...yep. A baby gate, we have one in our hallway to the other half of the house too.
