that is a load of rubbish, the lad says he wont's a dog for ferreting so i would say bedlington blood because they got a good nose high prey drive and will ferret all day long. Also a beddyx will catch you loads of rabbits on the lamp and even foxes. my two or 3/4 bedlington 1/4 greyhound and they stand at 20 inch they are best at ferreting but catch will on the lamp because they turn fast and trust me they fly in to foxes before the ban. a whippet is a good dog to but i think there to weak to be out all the time. not had a lot to do with the collie x but i would say they would be good because
