Fascinating question! If you asked me, I would ask what sort of dog? or which dog? If you said, "it doesn't matter", then I just get some random dog. It's a bit like a slideshow of dogs. If you asked me to describe it, then it would be some fantasy dog or I might zoom in on a dog that I actually know. I have bits of what could be called photographic memory. In school I would "snap" pages of notes and then in the exam recall the page and "read" it for the information required. I never actually tested it to see how many pages I could save and recall like that. Probably less than a roll of film. Will look at @r721's links. Very interested.
