If you go onto the grooming board and have a search, there are lots and lots of posts about handstripping.
You can learn how to do it. There is a DVD on the subject I believe (again, see the grooming board), or some people learn from their breeders who also show. I use a rubber band threaded through a metal comb, and it works a treat. It does the same as handstripping, removes the dead undercoat. Bingley is just seven months and I have my first go this weekend. He is usually a nightmare when being groomed, but he actually seemed to enjoy it. It's amazing how much I got off in just a short 5 minute session.
