What do you feel?

Fear is universally considered to be the worst emotion of all, and imagination may be the most powerful mental capacity that we have.  When you combine the two, the mind can uncontrollably slip into some terrifying places very quickly.  What did you feel when you first saw this photograph? 

Actually it’s a close up of the face of a very friendly dog.  His tail was wagging frantically when I took this photo, but without that knowledge your mind can conjure up perceptions of all sorts.
