Same for me on the wiper blade looking like a gun barrel. Maybe you should edit the description and just let people guess. The dog shows up after you get past the initial surprise.
As I mistook the (apparent) jeep door trim for a double-barrelled shotgun, the bag-toting middle-aged female about to be obscured in a step or two had my undue attention. The photographer's comment completely ruined the illusion, the high drama and the intrigue. :-/
