I'll start the ball rolling; MUST have Greyhound as the base.... then I'd like to see Saluki, Deerhound, Bedlinglton, Whippet, and even though I'm not a fan, Bull ! But is there any other breed you'd like to put to a Greyhound to produce a Lurcher ? I missed out Collie, simply because I've only had one Collie cross, and it was shite !! Doesn't mean they all are, but that's just my view !!
Cheers.
