There is always a ring of dogs well back from the line.
Every bird that gets pricked is immediately chased down and dispatched.
Remember, every one of those birds is going to market. Too shot up, and they become dog food.
Ideally, every bird snaps its head back and falls. In reality, the dogs (which have better eyesight than humans) identify, and then sweep up every pricked bird. They are real marvels. Picking up hundreds, possibly thousands, of pricked birds every season.
Even the busiest commercial estates are free from half eaten carcasses laying about the grounds.
The pickers really do their job well.
