I have a puppy buyer who is interested in getting started in showing. Any suggestions for a book I might refer him to that would detail show training and the point system? Looking for something simple.

AKC has a link with the point system that is pretty easy to understand:

and a beginner's guide to showing:

handling classes are the best way...plenty of people to ask questions and plenty of people from many breeds to be supportive at the shows.

I love the book Raising a Champion by John & Richards. Its written with the person new to showing in mind. I take handling classes with Carole and she said they wrote the book when they didn't have a good book to recommend to their puppy buyers with no conformation experience. Her website is (or try Amazon):
