Sorry I don't think I explained generalising very well.
Example (not huntiing dogs) Mrs B: "But my dog is so good at sit-stays at home!"
He might very well be, but if he has only practiced at home and not outside, on different surfaces, for different durations, from different distances, with different distractions, then we cannot expect him to do it perfectly first time like he does at home.
Another example: teaching pooch to wait at the door for you to go through first. He might do this every single time 100 times in a row. Go to the back gate where, to you and me, the concept is exactly the same. Without management he might rush straight in right past yoU!
