take a camera!!
best thing you can do is get there early.... find the hound area that your interested in, most of the activity will be around the covered area surrounded by kennels. there's some very good "real life" shots to be had, huntsmen putting hounds in kennels, collecting ring etc. if you want to photograph the hounds showing, push your way in early and go the collecting ring end with you back to toilets, get in that corner stood up and you will see it all.
there are different areas for old English, bassets, beagles, terriers etc, but noone really cares about them
