Well, often you can just get moving if you know how to recognize the dog is on game. But on a hot runner, where the dog is clearly blowing it out. I first try to go with, and if I can not keep up, I hit the hup whistle. One crisp quick toot. Never a collar. Now your punishing the dog for good behavior if you use the collar to make them stop on a runner. It needs a command. The whistle I and many use, is not alarming birds at all. Toot, dog sits till I get there, and I say high on, they continue. This can go on for a long way. But 99% of the time when a dog puts it's nose down, you can simply recognize it and follow them. And then shoot the bird or not. When it flushes, then the hup comes in again. If it is a hen, well your not calling your dog back from a half mile. But if your using a collar to stop a dog on a runner, as said, your asking for trouble. Hitting someone for doing the right thing so to speak. Now if you hit your whistle, and he does not listen to a command, that is when you can correct the dog. He is being corrected for bad behavior, and they do know the dif if you teach the command. A bird in flight is different. This is why a steady dog is less confusing to a dog. If steady, chasing without being released is bad behavior, and can be corrected with out screwing up the dog. Hitting an un steady dog because he chased a hen is now confusing the dog. And suddenly he may say screw you, I'm never going out to get that other dam bird either. Hence never wanting to retrieve.

PS we don't just dream this up LOL. We have seen many fine dogs screwed up by doing some of these things. Guilty myself. I just offer tried and true help here and there. If someone is receptive or not to it, it is a choice, and I can not worry about that. Life goes on. People near are always welcome to come and have fun training. If they want to help and be helped.
