The dog is like "Just don't sneeze. Don't twitch. Just be very still and maybe he wont notice me."
But they deleted the rest of the caption, "but if you run you will be lunch."
Its not Photoshopped ,
the San Diego Zoo has Cheetahs and dog together in the same pen, raised
together since they were born, its keeps the Cheetahs calm in front of
large crowds. I have pictures.
