I was shooting some other wildlife off to the right when out of the corner of my eye I saw the dog approach the goose and thought this could be interesting... So I quickly turned to catch this shot, but didn't have any time to adjust the exposure for an appropriate shutter speed given the change in lighting. Hence, the goose is not as sharp as I would like, but I thought the interaction of these two fit this week's theme better that some of the others images I captured that day.
[edit] Even though I believe the horizon was level in the first post, it appears slanted due to the camera view not being perpendicular to the shoreline. After looking at it again, it was a little distracting so I "straightened" it and re-posted.
