David peered down at the chewed rope end in his hands. Dusty had freed himself again. Dropping the rope, the boy ran to the coop. He opened the door and counted the chickens, pointing his flashlight at each one. They clucked softly and blinked their eyes. All 18 were there. The week before there had been 20 hens, but Dusty, the yearling Labrador retriever David had bought for hunting, had killed two. After the killing, David had promised his father that he would work with the dog, tying him up until they could be sure he would do no more damage.
