Ran em to ground a few times, best one i remember was over 40 yrs ago in a wood , problem was we had a terrier running with the lurchers and it got to the hole before we did and followed it down, now i have done a fair bit of terrier work over the yrs and i will tell you now this dog took a hell of a pounding before we got it out, we had to kill the hare as it was mauled on its arse end , allways sticks in my mind this creature really deserved to live.
