pure bred whippets just dont have the same durability, stamina , nose or gameness as the well bred beddy whippet.imo
So pace is not important?? as no beddy/whippet is as fast as a working strain whippet and alot of places it makes a big difference.
as long as theyre fast enough ,thatll do,they dont need to be racing machines, id rather have a dog that can go all day, and all night
