Sorry to go off the topic a bit but i have a kelpi collie cross, i have trained her to work sheep very good driving dog, use her out with the terrier and lurcher, and she loves to hunt with a keen nose, but what she lacks is the killer instinct, where she likes the hunt more than the kill bit like a hound. Temped to cross her to get a nice rabbitin dog, would a keen greyhound over her cure this? Apart from this shes tough as old boots, quick, agile, over obedient and loves to please.
