yeah, I think it's only fairly recently, less than 100 years, that lurchers have been classified as such, as predominantly collie/herding dog x's. As you say, anything that could hunt and catch would've been used. I like some of the less sighthoundy types and reverse 3/4 breds etc, but where we work ours you need a dog with plenty of pace, and I don't mean to be contentious, but even some 1/2 x collie greyhounds wouldn't catch too much on some of the land we run ours on, but like I say, I do like some less sighthoundy types
