No mate; I had Whippets and Whippet crosses since the 60's, and the Whippet probably had it's hay-day in the 60's and 70's. But, yes, it IS, gladly, making a strong comeback, but it will never usurp the Greyhound as a base breed for Lurcher breeding.
Cheers.
as a wiser man than me ill take your word for it mate atb
