Hi John, I live close to Jimmy , he has had top collies for years, I know his sons well enough to , I know what type of dog you are on about as i hunted them hills since a child . So I understand where you are coming from having had that type of curr dog in the past, fair play as they was once a plenty around these parts , most folk had them but not anymore , the best dogs I saw where bred as you have described, Evan though I don’t keep the cross talked about I am a admirer, all the best .
