It is not a proper lurcher, the original lurcher is a cross between a greyhound and a collie, although any sighthound cross tends to be called a lurcher these days.
Of course we must bow to lankeelas superior knowledge ...but there is also something called a "Longdog" . A greyhound crossed with a whippet http://www.reference.com/browse/wiki/Longdog
That was my thinking, too, BOO, sadly I got here a bit late! lol. I didn't realise a lurcher was that type of cross. You learn something new...etc. :) Lisax
