you will struggle to get an adult saluki bitch. theres not many about even if you have got £££. even if you did get one you might have to wait a year for it to come in season, (if it comes in season)
sometimes they don't pass the pups very easy, and need a caesarian which is £600.
theres no short cuts really, if your committed the best thing to do is buy a saluki bitch pup, for £350/£450 bring it up like a lurcher, for 3 years or more, and if it catches the stuff you want successfully, then start your first x line from there.
