Not sure I'd go with a full sighthound/coursing type for a bushing/rabbiting lurcher I'd be looking for something a bit more able to take direction and be biddable/controllable as poss. But thats just my opinion I'm sure there'll be some out there doing the job.
I'd probably agree. I'd go for something with maybe some collie blood and whippet, if you were going to 'build' the ideal bushing dog, quick acceleration, good brain, decent nose, some jacket etc.
