I been lucky seen a lot of workin grey all the 1 I seen that had long workin carer all was weighed in as pup, make sense really track dog dont need or learn sense running around in big circle. I wud never bring 1 in off a track I say more failed attempts of making 1 take on role of lurcher for a lifetime, in less learnt from pup and gave field craft. u be shocked they hav more blow then peeps give em credit and if sensible quite sterdie but wat put people off is to get good breedin in grey u gotta open ur wallet and get ya wonga out they aint cheap But IMO well worth the investmentvery fair po
