Pidge ,years ago Trill and I went up to hancocks and i bought a3/4 greyxborder,he turned out to be a very good dog ,soft mouthed ,would take all quarry and I used him to the gun as well,in later years MY mate bred his Bitch a 1/8 beardie/ 1/8 border xgreythis litter was very fast ,with fair noses and a lot of drive ,I won doubled uo coursing stakes with mine ,and my mate who bred the litter did the same,for myself ,Id go for the 3/4 g x 1/4 border,I think they are more biddable,I dont know how many dogs youve had ,but if you are relatively new to the game ,that would be my choice,any way b
