Border Collie stalking a stick

A black and white border collie stands in the water at a beach, waiting for the owner (out of shot) to throw a stick. The dog is prepared to take action, with the head lowered and extended and eyes focused. Its tongue is out, curled back over its nose as it licks the sea water from its muzzle. The curve of the beach and local homes can be seen in the background. Sea is calm with small waves.
