Dogs Train Their Humans to Keep Petting Them

Have you ever been petting a dog who lets you know in no uncertain terms that you've cut short the behavior prematurely and need to report to duty again asap? My dog has a little move we call the noseflip. One bump of his nose underneath your now resting hand will make the hand go flying in the desired petting direction. Aaand repeat. It seems as if every one of the canines shown here have mastered their own set of unique moves.
