A tug-of-war is developing. The Labrador - front legs stretched out stiff, brakes full on - has the head of a yard brush clamped in his jaws, bristles either side of his face. At the opposite end of the brush, two small children are hauling hard on the handle. Suddenly the dog lets go. The brush and the children go flying. With a Leica compact, you´d have the perfect picture...of a dog laughing!
