i know a few lads that say their dogs are too fast for hares ,i disagree .I think they are too hard going and put in too much drive in the killing of them and end up going too far away from the hare when they strike.Iv 2 good fox lurchers at the moment but the only fault id have is they put everything into the strike and end up a few yards off the fox if they miss .Some might call it too fast i just call it gameness.JMO
