i bred a litter of bull whippet/ bull grey collie grey pups. one bitch threw to the whippet, I gave her to a mate, she would completely ignore rabbits either daytime or on the lamp, But Hares well there another story, The bloke who had her was no big lurcher man, he had spaniels and beat on a couple of the local shoots, Everyday he would walk his dogs around the local area. This bitch caught 32 hare on 32 consecutive days just whilst out on his morning walk.
