We blinked and in that fraction of a second, I realized we had our own version of Morse Code.
I will attempt to translate the interaction in the live photo below.
Human: (Blink – Squint – Blink) You are a Goooooood Boy!
Jack: (Left Eye Blink – Right Eye Wink + tail wag) I luv you!
After that, I found myself wondering, as I often do if all dogs and their humans have their own nonverbal conversation.
