I have a non-ped whippet and a pure whippet, my non-ped out shines my pure every time! she's not at all scared to get stuck in and have a go at anything, where as my pure whippet won't go threw bushes or jump over fences etc
but he is great on the open runs, as is my whippet/grey bitch, so my non-ped bitch flushes the bunnies out and then my pure whippet lad takes over and runs them down, he's also quite good at retriving them, but my bitch is better and faster, they do work well as a team though
