Being in the industry, if I had this problem I'd contact the dog door
with a wide gap contact and set it up as an alarm point.  I'd attach a
RFID tag to the dog's collar and use a long range reader to shunt the
contact when the dog was approaching the door.  Anything other than
the dog would cause an alarm if the dog door was opened.
