I watched Harry Enfield and Paul Whitehouse last night in 'Harry & Paul' and was very interested in 'The Royal Henley Northerner Show 2008'. So I have a couple of questions; Where can you get a Northerner to show; are there specialist breeders? What are the fundamental differences between specific breeds? Are they easy to train (I guess some breeds easier than others)? Are they expensive to keep (food, drink versus benefits etc)? Can they turn nasty?
