When Ziva is relaxed and not actively searching for the location of a sound, the tops of her ears will flop in rhythm with her footsteps. If I had something like a GoPro, I would arrange a doggie-neck-cam to show it from a close perspective. This is my first stab at showing the effect through iPhone video, shot while we walked and I held the leash. I used slow-motion, but at the beginning and the end you'll see a brief snatch of normal (walking) speed.
Next goals: to capture the excitement of a trot, then a gallop!
Later, she was ready for a nap, but that didn't mean the exercise was over for the day.
However, that's it for photos, for now.
