So the way my parents have it set up for our dog is that he’s allowed to go all over back yard and sleep inside but in one spot which is right in front of doggie door once he enters inside the house from it. My dog is 8 years old and is American staffordshire terrier breed. Lately he’s been going to the back yard and sitting in front of the backyard door and just stares at the door( the one that enters the house) he also sits there and barks at night and chews up the slippers there) he’s been spreading his feces with his feet around as well. I scold him and use the technique my neighbor had taught me for when my dog mishaves( learned 7.5 years ago from neighbor, been using it) which is to rub the dogs face in what he did. So my question is why is our dog misbehaving and how do i fix it.
