Wow. That's very helpful.

In the meantime, I installed a regular medium-sized dog door today. The door already has a hole in it, so it's "ruined" anyway. I've got a skinny dog, so she fits through the medium-sized door. But if this doesn't work out, the door you posted may be the ticket. The other automatically-unlocking doors I have found on the net have had mixed reviews.
