I have seen men training dogs for bird hunting

I have seen men training dogs for bird hunting, who would treat the dog most cruelly and claim that a dog could not be trained to work a bird successfully under any other treatment. Though I have seen others train the same breed of dogs to work a bird to perfection and that their most harsh treatment would be a tap or two with a little switch. I will say that one who cannot understand the wag of a dog's tail, the wistful gaze of the eye, the quick lifting of the ears, the cautious raising of a foot, and above all, treat his dog as a friend, need expect his dog to be but little else than a nuisance on the trap line.
