D.O.P.-T.

That mostly black puppy I once photographed, which grew up into a gangly and very friendly dog, used to be able to stick her entire head through the gap between the gatepost and the gate to her yard. The guy carefully adjusted either one or both (metal gatepost, heavy sliding gate). This evening on walkies, as we passed by, she ran to the gate ... and stuck her entire head through the gap again.
