When Sadie was a puppy, she would follow me everywhere. There was no such thing as privacy in my house. Of course that was to be expected with a new puppy and I enjoyed the constant companionship. There was just one problem – Sadie absolutely hated closed doors. As soon as she heard a door close, Sadie would go running to see who was trying to keep her out and why. She would cry and scratch at bathroom doors, bedroom doors, even closet doors. It was like she was afraid that if a door was closed, then she was missing something exciting on the other side.
