As you exit space mountain, one of the last scenes has a mechanical dog. He is wearing a classic mickey necklace.

On the exit ramp of Space Mountain- check out the dog's collar.

Unfortunately, this classic Mickey seems to disappear at times. (See third photo).

I just want to send in a follow-up to the reported missing tag from the Space Mountain dog. The tag is actually a long running fight between Cast Members and DACS (Digital Animation Control System, which is the maintenance/engineering department). When I was working there, we got a new tag and had all the CM's initials engraved on it and put it on the dog. Unfortunately, we believe it is DACS who takes it off at night while we are gone, and we kept replacing it. It's a tradition with CM's to make a new one and replace it when we can. (Armand)
