Maybe you mis-read the post mate; I wasn't crabbing any type of dog ! I think the Coursing dog and the Non-Ped are unbeatable in their own feilds, and can still do other things, so certainly not "one trick ponies"
Cheers.
ive been around non ped whippets for nearly40yrs as a youngen we still caught rabbit/hare/fox
with these dogs some big some as small as 23lb in weight
they can adapt to anything feild or racing which our present dogs still do ive still got
the line of a old dog we had in my bullxs
there pedigree cant be trace back over 40 yrs alot more than some folk can say a
