i asked my dad his opinion on this last night as hes done alot more than me and he said the best deer dog he owned was a lurcher he rescued from the kennels full of mange and underweight so the breeding was unknowen seen old photos and it had a bullx head but was racy and muscular at the same time if you know what i mean, anyway he said it would bring it down and go for the throat
sadly got knocked over whilst chasing a roe, ill have to put some of his old pics up if hel let me
