I need ideas on training my dog to drive through lots of scent on the way to a mark or blind and not break down and hunt the scented area or get hung up in dragback. Last weekend WildThang broke down on the long retired gun and started hunting in the dragback. She has done this other times too, even though I set this up in training and she kept on going through my scented area. The few times she did break down I sat her and cast her back to the bird. This dog is almost 6 and has retreived hundreds of ducks while hunting so when she hits scent she figures it's time to hunt. Suggestions on how to train her to keep going would be appreciated.
