For the lads who work these type of dogs, what do you think terrier adds to the mix. I'm after a bushing dog next season, and I was thinking pure cocker. I like how they hunt and I like the fact that they retrieve, which would come in handy lamping rabbits with the rimmy plus the odd bird or 2. My only concern about a pure cocker is that if grabbed a fox in the cover and took a bite to the nose, would this put it off working fox? Is this why some add terrier blood?
