I wasn't having a good day and I knew who to turn to... my golden giggle maker! I remember one day someone taught me how to make your dog sneeze, in gentle way of course.
have your thumb and index fingertip over their muzzle - just right before/on the wet noseline, then shake little that part as fast as you can for few seconds and anytime your dog will ... achoo!
not only crayola sneezed, he wagged silly, pushing his head under my arm, bowing laugh! then we do it over again and again .. teehee .. now who couldn't giggle to sleep?
