A fellow was walking his dog Maggie w/o a leash. It sniffed its way through the grass outside the grove of trees I was in, then headed to the left. Seconds later, a coyote was outside the grove, moving along the edge. It stopped in the sun, just outside the trees. The coyote was watching the dog and may have been unaware that I was watching it from just meters away. I had the tripod/camera/lens set up, pointed the other way, and didn't want to disturb the scene. The dog made a run at the coyote, the coyote ran to the right, they exchanged words, and the dog returned to its owner (and a leash). The coyote followed them from a safe distance.
