My husband had a lab he hunted pheasant with. She was never "trained", hunted on instinct. Once she leapt up and retrieved a pheasant he missed, nabbed it right out of the air. He had to let it go of course but she gave him the "must I do it myself" look. Another time, she was retrieving a shot bird, and a hawk decided it was nice of my husband to shoot it's next meal. Shadow would have NO part of that, she managed to get the pheasant from the hawk. She was ALL attitude.
Shadow lived to be 15 1/2, he 15th birthday was 4 days after opening pheasant season. He took her out knowing she might die if she goes, but it would kill her to stay home. She put up a pheasant that day. I often wonder what she would have been like had she been trained.
