What you're saying is some people MISTAKE (or misrepresent) a "game" pick up, where a dog is not willing to continue, but the owner tries to pass it off as a game pickup.

or dog that are picked up that are willing to continue, while a Labrador even would have continued.

think w'r not understanding eachother.
