Are you talking about the white dog in the pic where I'm holding them both? That one is saluki collie Whip grey.....but both white dogs can put a shift in.......neither of them are mine both belong to lads that give me a hand with the rabbiting  only the brindle is mine, all 3 have there own unique styles from marking to how they work a warren and all work well together which is nice to see......tbf I know alot of lads wouldn't chose a dog with saluki in the mix for a ferreting dog but can't fault them really always put a shift in, can be a bit over keen sometimes cheers mate hope you have a
