lad here in ireland, about 19 years ago, bought a pure saluki from uk, he had seen the parents work well in some decent big fields and catch a lot of stuff, he was mad to get a pup from this mating ans payed £500 for a bitch pup at that time.
he had a awfull time raising the pup, even though he had done a lot of research into it and was very patient with the pup, after 3 years, the saluki could not catch a thing!, it just did not try and once got hold of a bunny, only letting it go, after the bunny kicked about!
to say he was down about it, was a understatement!
I think he was just unlucky
