you cant go wrong with a collie/greyhound, collie for brains and greyhound for speed. its as simple as that if you take your dog out for excersise regular it will build up stamina and harden its feet, use small regular training sessions when its a pup to teach it basic obediance and before long you'll have a good hunting companion. Don't over complicate things keep it simple. hope that's helped, i also know some good lurcher breeders who i could put you in contact with if you need.
