"Gaze-following" is what it is called. Our dog Cleo does it, and has done it since we adopted her years ago.
If they can track with their nose, why can't they track with their eyes? We always thought this habit only confirmed that dogs are smart. Like poker players, they know to follow our visual cues. And we humans "tell" them or transmit our intentions.
We can only hope to figure out what their tail is transmitting. I believe they have the upper hand, or paw, in this relationship, don't you?
Does your dog follow your gaze? Have you noticed them tracking your movements? We'd love to know your thoughts and comments.
