I'm afraid I'll forget why I am entering that room. Usually happens when I get to the middle of the room.

Oh, getting older!

I opened the door for him to come inside, but I opened it too forcefully and it bounced off the wall and hit Bert. Six years later, he still hesitates whenever he comes inside, 2-4 times a day. I imagine domwthing similar probably happened to this dog at one time.

Aussies are very smart and sensitive and a little crazy too.

Looks like he has PTSD from a previous experience he had from entering a room so he now walks in backwards to make sure he can get a quick getaway if he has to.
