At the Kubrick archive, the dog is not well. (Via Metafilter) Access to the Kubrick archive leads to strange discoveries:

… a large room painted blue and filled with books. … "Every book in this room is about Napoleon!"

"…just about every ghost book ever written..."

"…a box containing photographs of the exteriors of maybe every mountain hotel in the world."

...fan letters … perfectly preserved. They are not in the least bit dusty or crushed. … Each fan box contains perhaps 50 orange folders. ... inside each folder are all the fan letters that came from [a] particular place in any one year. Kubrick has handwritten "F-P" on the positive ones and "F-N" on the negative ones. The crazy ones have been marked "F-C".

… a box marked "Sniper head - scary". Inside, wrapped in newspaper, is an extremely lifelike and completely disgusting disembodied head of a young Vietnamese girl, the veins in her neck protruding horribly, her eyes staring out, her lips slightly open, her tongue just visible.

… two boxes that read Shadow On The Sun. … The boxes contain two volumes of what appears to be a cheesy sci-fi radio drama script. The story begins with a sick dog: "Can you run me over to Oxford with my dog?" says the dog's owner. "He's not very well. I'm a bit worried about him, John." This is typed. Kubrick has handwritten below it: "THE DOG IS NOT WELL."
