She beat the system
What can the little doggo do when the house rules are set by humans? They find some or the other way that will turn the situation in their favor. Just like the stepping out of the house rule that this dog played.
The smart dog knows that if she steps out, the humans will shut the door and she doesn’t want that. At the same time, she wants the taste of freedom and a little fresh air. So cunningly she sits with her front paws and head facing the street and her behind inside the house. Well played little dog, well played!
