I have been duck hunting for bout 16 yrs now and we always have a "designated dog". (Usually the one who shows up to the boat ramp late takes that honor.) I have hunted with several different folks and their dogs over the years and "Water Dog by Richard Wolters" always comes up. Whiskers could not have put it any better when he said "Labs are pleasures so reward them." When a dog is born, the first thing he has to figure out is how to get food and as he grows he consistantly has to figure that out. Use this to your advantage!
