http://www.chicagonow.com/training-the-wolf/2013/06/positive-reinforcement-failure/There are certain behaviors that your dog engages in that are self-rewarding. This means that the behavior is more enjoyable than any treat or praise you can offer. The booze is better than the biscuit. This is especially true for the hunting dog. For positive reinforcement to work, the treat or reward has to be the best thing available at the time. For the hunting dog, there is nothing he loves more than the animals he hunts, and we humans cannot compete.
